Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530704, here are decompositions:

3 + 31530701 = 31530704
43 + 31530661 = 31530704
61 + 31530643 = 31530704
67 + 31530637 = 31530704
97 + 31530607 = 31530704
181 + 31530523 = 31530704
313 + 31530391 = 31530704
523 + 31530181 = 31530704

Showing the first eight; more decompositions exist.

IPv4 address
