Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450984, here are decompositions:

17 + 31450967 = 31450984
23 + 31450961 = 31450984
137 + 31450847 = 31450984
197 + 31450787 = 31450984
263 + 31450721 = 31450984
317 + 31450667 = 31450984
401 + 31450583 = 31450984
443 + 31450541 = 31450984

Showing the first eight; more decompositions exist.
