Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610974, here are decompositions:

107 + 31610867 = 31610974
233 + 31610741 = 31610974
251 + 31610723 = 31610974
401 + 31610573 = 31610974
641 + 31610333 = 31610974
683 + 31610291 = 31610974
743 + 31610231 = 31610974
761 + 31610213 = 31610974

Showing the first eight; more decompositions exist.
