Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496436, here are decompositions:

7 + 31496429 = 31496436
17 + 31496419 = 31496436
19 + 31496417 = 31496436
47 + 31496389 = 31496436
67 + 31496369 = 31496436
107 + 31496329 = 31496436
173 + 31496263 = 31496436
227 + 31496209 = 31496436

Showing the first eight; more decompositions exist.
