Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463374, here are decompositions:

11 + 31463363 = 31463374
53 + 31463321 = 31463374
113 + 31463261 = 31463374
227 + 31463147 = 31463374
251 + 31463123 = 31463374
311 + 31463063 = 31463374
443 + 31462931 = 31463374
563 + 31462811 = 31463374

Showing the first eight; more decompositions exist.
