Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479944, here are decompositions:

127 + 31479817 = 31479944
151 + 31479793 = 31479944
367 + 31479577 = 31479944
487 + 31479457 = 31479944
523 + 31479421 = 31479944
607 + 31479337 = 31479944
673 + 31479271 = 31479944
883 + 31479061 = 31479944

Showing the first eight; more decompositions exist.
