Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494864, here are decompositions:

47 + 31494817 = 31494864
83 + 31494781 = 31494864
97 + 31494767 = 31494864
101 + 31494763 = 31494864
127 + 31494737 = 31494864
151 + 31494713 = 31494864
157 + 31494707 = 31494864
173 + 31494691 = 31494864

Showing the first eight; more decompositions exist.
