Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574316, here are decompositions:

13 + 31574303 = 31574316
19 + 31574297 = 31574316
83 + 31574233 = 31574316
113 + 31574203 = 31574316
223 + 31574093 = 31574316
269 + 31574047 = 31574316
317 + 31573999 = 31574316
349 + 31573967 = 31574316

Showing the first eight; more decompositions exist.
