Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494984, here are decompositions:

5 + 31494979 = 31494984
41 + 31494943 = 31494984
47 + 31494937 = 31494984
61 + 31494923 = 31494984
97 + 31494887 = 31494984
167 + 31494817 = 31494984
263 + 31494721 = 31494984
271 + 31494713 = 31494984

Showing the first eight; more decompositions exist.
