Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464984, here are decompositions:

11 + 31464973 = 31464984
17 + 31464967 = 31464984
37 + 31464947 = 31464984
43 + 31464941 = 31464984
101 + 31464883 = 31464984
157 + 31464827 = 31464984
163 + 31464821 = 31464984
197 + 31464787 = 31464984

Showing the first eight; more decompositions exist.
