Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537762, here are decompositions:

41 + 31537721 = 31537762
71 + 31537691 = 31537762
131 + 31537631 = 31537762
281 + 31537481 = 31537762
293 + 31537469 = 31537762
353 + 31537409 = 31537762
449 + 31537313 = 31537762
491 + 31537271 = 31537762

Showing the first eight; more decompositions exist.

IPv4 address
