Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510036, here are decompositions:

29 + 31510007 = 31510036
263 + 31509773 = 31510036
353 + 31509683 = 31510036
419 + 31509617 = 31510036
443 + 31509593 = 31510036
479 + 31509557 = 31510036
617 + 31509419 = 31510036
863 + 31509173 = 31510036

Showing the first eight; more decompositions exist.
