Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494764, here are decompositions:

43 + 31494721 = 31494764
73 + 31494691 = 31494764
127 + 31494637 = 31494764
181 + 31494583 = 31494764
211 + 31494553 = 31494764
337 + 31494427 = 31494764
463 + 31494301 = 31494764
523 + 31494241 = 31494764

Showing the first eight; more decompositions exist.
