Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463320, here are decompositions:

3 + 31463317 = 31463320
59 + 31463261 = 31463320
71 + 31463249 = 31463320
107 + 31463213 = 31463320
173 + 31463147 = 31463320
197 + 31463123 = 31463320
233 + 31463087 = 31463320
257 + 31463063 = 31463320

Showing the first eight; more decompositions exist.
