Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605496, here are decompositions:

5 + 31605491 = 31605496
53 + 31605443 = 31605496
89 + 31605407 = 31605496
233 + 31605263 = 31605496
239 + 31605257 = 31605496
257 + 31605239 = 31605496
353 + 31605143 = 31605496
449 + 31605047 = 31605496

Showing the first eight; more decompositions exist.
