Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476998, here are decompositions:

67 + 31476931 = 31476998
127 + 31476871 = 31476998
151 + 31476847 = 31476998
199 + 31476799 = 31476998
271 + 31476727 = 31476998
307 + 31476691 = 31476998
367 + 31476631 = 31476998
499 + 31476499 = 31476998

Showing the first eight; more decompositions exist.
