Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479762, here are decompositions:

5 + 31479757 = 31479762
19 + 31479743 = 31479762
23 + 31479739 = 31479762
43 + 31479719 = 31479762
113 + 31479649 = 31479762
173 + 31479589 = 31479762
211 + 31479551 = 31479762
263 + 31479499 = 31479762

Showing the first eight; more decompositions exist.
