Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463212, here are decompositions:

89 + 31463123 = 31463212
113 + 31463099 = 31463212
149 + 31463063 = 31463212
233 + 31462979 = 31463212
281 + 31462931 = 31463212
311 + 31462901 = 31463212
401 + 31462811 = 31463212
419 + 31462793 = 31463212

Showing the first eight; more decompositions exist.
