Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463194, here are decompositions:

47 + 31463147 = 31463194
71 + 31463123 = 31463194
107 + 31463087 = 31463194
131 + 31463063 = 31463194
263 + 31462931 = 31463194
293 + 31462901 = 31463194
317 + 31462877 = 31463194
383 + 31462811 = 31463194

Showing the first eight; more decompositions exist.
