Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479776, here are decompositions:

7 + 31479769 = 31479776
19 + 31479757 = 31479776
37 + 31479739 = 31479776
79 + 31479697 = 31479776
127 + 31479649 = 31479776
157 + 31479619 = 31479776
199 + 31479577 = 31479776
277 + 31479499 = 31479776

Showing the first eight; more decompositions exist.
