Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464766, here are decompositions:

149 + 31464617 = 31464766
257 + 31464509 = 31464766
617 + 31464149 = 31464766
719 + 31464047 = 31464766
857 + 31463909 = 31464766
887 + 31463879 = 31464766
1049 + 31463717 = 31464766
1259 + 31463507 = 31464766

Showing the first eight; more decompositions exist.
