Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479764, here are decompositions:

7 + 31479757 = 31479764
67 + 31479697 = 31479764
223 + 31479541 = 31479764
307 + 31479457 = 31479764
457 + 31479307 = 31479764
487 + 31479277 = 31479764
523 + 31479241 = 31479764
691 + 31479073 = 31479764

Showing the first eight; more decompositions exist.
