Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463984, here are decompositions:

43 + 31463941 = 31463984
73 + 31463911 = 31463984
127 + 31463857 = 31463984
157 + 31463827 = 31463984
241 + 31463743 = 31463984
271 + 31463713 = 31463984
397 + 31463587 = 31463984
457 + 31463527 = 31463984

Showing the first eight; more decompositions exist.
