Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510564, here are decompositions:

3 + 31510561 = 31510564
11 + 31510553 = 31510564
23 + 31510541 = 31510564
47 + 31510517 = 31510564
131 + 31510433 = 31510564
167 + 31510397 = 31510564
347 + 31510217 = 31510564
431 + 31510133 = 31510564

Showing the first eight; more decompositions exist.
