Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463356, here are decompositions:

3 + 31463353 = 31463356
107 + 31463249 = 31463356
233 + 31463123 = 31463356
257 + 31463099 = 31463356
269 + 31463087 = 31463356
293 + 31463063 = 31463356
467 + 31462889 = 31463356
479 + 31462877 = 31463356

Showing the first eight; more decompositions exist.
