Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510334, here are decompositions:

13 + 31510321 = 31510334
223 + 31510111 = 31510334
241 + 31510093 = 31510334
313 + 31510021 = 31510334
367 + 31509967 = 31510334
421 + 31509913 = 31510334
571 + 31509763 = 31510334
577 + 31509757 = 31510334

Showing the first eight; more decompositions exist.
