Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468956, here are decompositions:

37 + 31468919 = 31468956
53 + 31468903 = 31468956
107 + 31468849 = 31468956
163 + 31468793 = 31468956
179 + 31468777 = 31468956
199 + 31468757 = 31468956
229 + 31468727 = 31468956
257 + 31468699 = 31468956

Showing the first eight; more decompositions exist.
