Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510436, here are decompositions:

3 + 31510433 = 31510436
37 + 31510399 = 31510436
73 + 31510363 = 31510436
127 + 31510309 = 31510436
193 + 31510243 = 31510436
487 + 31509949 = 31510436
523 + 31509913 = 31510436
547 + 31509889 = 31510436

Showing the first eight; more decompositions exist.
