Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510076, here are decompositions:

67 + 31510009 = 31510076
109 + 31509967 = 31510076
127 + 31509949 = 31510076
163 + 31509913 = 31510076
193 + 31509883 = 31510076
313 + 31509763 = 31510076
337 + 31509739 = 31510076
379 + 31509697 = 31510076

Showing the first eight; more decompositions exist.
