Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540496, here are decompositions:

3 + 31540493 = 31540496
7 + 31540489 = 31540496
79 + 31540417 = 31540496
157 + 31540339 = 31540496
199 + 31540297 = 31540496
283 + 31540213 = 31540496
307 + 31540189 = 31540496
349 + 31540147 = 31540496

Showing the first eight; more decompositions exist.
