Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463996, here are decompositions:

37 + 31463959 = 31463996
103 + 31463893 = 31463996
139 + 31463857 = 31463996
199 + 31463797 = 31463996
229 + 31463767 = 31463996
283 + 31463713 = 31463996
307 + 31463689 = 31463996
409 + 31463587 = 31463996

Showing the first eight; more decompositions exist.
