Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494960, here are decompositions:

11 + 31494949 = 31494960
17 + 31494943 = 31494960
23 + 31494937 = 31494960
37 + 31494923 = 31494960
41 + 31494919 = 31494960
53 + 31494907 = 31494960
73 + 31494887 = 31494960
151 + 31494809 = 31494960

Showing the first eight; more decompositions exist.
