Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476518, here are decompositions:

19 + 31476499 = 31476518
61 + 31476457 = 31476518
67 + 31476451 = 31476518
127 + 31476391 = 31476518
331 + 31476187 = 31476518
349 + 31476169 = 31476518
421 + 31476097 = 31476518
487 + 31476031 = 31476518

Showing the first eight; more decompositions exist.
