Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605676, here are decompositions:

83 + 31605593 = 31605676
233 + 31605443 = 31605676
257 + 31605419 = 31605676
269 + 31605407 = 31605676
419 + 31605257 = 31605676
467 + 31605209 = 31605676
647 + 31605029 = 31605676
659 + 31605017 = 31605676

Showing the first eight; more decompositions exist.
