Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529482, here are decompositions:

3 + 31529479 = 31529482
11 + 31529471 = 31529482
233 + 31529249 = 31529482
239 + 31529243 = 31529482
263 + 31529219 = 31529482
269 + 31529213 = 31529482
401 + 31529081 = 31529482
641 + 31528841 = 31529482

Showing the first eight; more decompositions exist.

IPv4 address
