Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494946, here are decompositions:

3 + 31494943 = 31494946
23 + 31494923 = 31494946
59 + 31494887 = 31494946
137 + 31494809 = 31494946
179 + 31494767 = 31494946
233 + 31494713 = 31494946
239 + 31494707 = 31494946
257 + 31494689 = 31494946

Showing the first eight; more decompositions exist.
