Connections to High Numbered Ports?

I'm seeing ongoing connections to high numbered ports from a variety of IP addresses

Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 207.58.131.105:53264 64.12.138.89:25 CLOSE
tcp 0 1 207.58.131.105:53558 83.33.112.126:113 SYN_SENT

Generally I expect to see connections to
207.58.131.105:80 (HTTP Traffic)
207.58.131.105:25 (POP Traffic)
207.58.131.105:110 (SMTP Traffic)

What in the heck is going on with port 53264 and 53558?!
