Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574814, here are decompositions:

41 + 31574773 = 31574814
67 + 31574747 = 31574814
113 + 31574701 = 31574814
127 + 31574687 = 31574814
137 + 31574677 = 31574814
157 + 31574657 = 31574814
251 + 31574563 = 31574814
283 + 31574531 = 31574814

Showing the first eight; more decompositions exist.
