Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540316, here are decompositions:

7 + 31540309 = 31540316
19 + 31540297 = 31540316
103 + 31540213 = 31540316
109 + 31540207 = 31540316
127 + 31540189 = 31540316
193 + 31540123 = 31540316
307 + 31540009 = 31540316
349 + 31539967 = 31540316

Showing the first eight; more decompositions exist.
