Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494976, here are decompositions:

53 + 31494923 = 31494976
89 + 31494887 = 31494976
167 + 31494809 = 31494976
239 + 31494737 = 31494976
263 + 31494713 = 31494976
269 + 31494707 = 31494976
467 + 31494509 = 31494976
479 + 31494497 = 31494976

Showing the first eight; more decompositions exist.
