Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476974, here are decompositions:

43 + 31476931 = 31476974
103 + 31476871 = 31476974
127 + 31476847 = 31476974
241 + 31476733 = 31476974
271 + 31476703 = 31476974
283 + 31476691 = 31476974
367 + 31476607 = 31476974
457 + 31476517 = 31476974

Showing the first eight; more decompositions exist.
