Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476128, here are decompositions:

31 + 31476097 = 31476128
97 + 31476031 = 31476128
199 + 31475929 = 31476128
331 + 31475797 = 31476128
349 + 31475779 = 31476128
379 + 31475749 = 31476128
547 + 31475581 = 31476128
727 + 31475401 = 31476128

Showing the first eight; more decompositions exist.
