Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510562, here are decompositions:

73 + 31510489 = 31510562
103 + 31510459 = 31510562
163 + 31510399 = 31510562
199 + 31510363 = 31510562
241 + 31510321 = 31510562
541 + 31510021 = 31510562
571 + 31509991 = 31510562
613 + 31509949 = 31510562

Showing the first eight; more decompositions exist.
