Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496686, here are decompositions:

17 + 31496669 = 31496686
113 + 31496573 = 31496686
149 + 31496537 = 31496686
167 + 31496519 = 31496686
197 + 31496489 = 31496686
257 + 31496429 = 31496686
269 + 31496417 = 31496686
317 + 31496369 = 31496686

Showing the first eight; more decompositions exist.
