Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479866, here are decompositions:

37 + 31479829 = 31479866
73 + 31479793 = 31479866
97 + 31479769 = 31479866
109 + 31479757 = 31479866
127 + 31479739 = 31479866
277 + 31479589 = 31479866
307 + 31479559 = 31479866
349 + 31479517 = 31479866

Showing the first eight; more decompositions exist.
