Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530804, here are decompositions:

5 + 31530799 = 31530804
7 + 31530797 = 31530804
31 + 31530773 = 31530804
101 + 31530703 = 31530804
103 + 31530701 = 31530804
163 + 31530641 = 31530804
167 + 31530637 = 31530804
197 + 31530607 = 31530804

Showing the first eight; more decompositions exist.

IPv4 address
