Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537102, here are decompositions:

5 + 31537097 = 31537102
53 + 31537049 = 31537102
59 + 31537043 = 31537102
101 + 31537001 = 31537102
239 + 31536863 = 31537102
281 + 31536821 = 31537102
383 + 31536719 = 31537102
563 + 31536539 = 31537102

Showing the first eight; more decompositions exist.

IPv4 address
