Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479206, here are decompositions:

79 + 31479127 = 31479206
223 + 31478983 = 31479206
487 + 31478719 = 31479206
607 + 31478599 = 31479206
613 + 31478593 = 31479206
727 + 31478479 = 31479206
883 + 31478323 = 31479206
919 + 31478287 = 31479206

Showing the first eight; more decompositions exist.
