Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476902, here are decompositions:

31 + 31476871 = 31476902
73 + 31476829 = 31476902
103 + 31476799 = 31476902
199 + 31476703 = 31476902
211 + 31476691 = 31476902
271 + 31476631 = 31476902
619 + 31476283 = 31476902
733 + 31476169 = 31476902

Showing the first eight; more decompositions exist.
