Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476888, here are decompositions:

7 + 31476881 = 31476888
17 + 31476871 = 31476888
41 + 31476847 = 31476888
59 + 31476829 = 31476888
67 + 31476821 = 31476888
89 + 31476799 = 31476888
197 + 31476691 = 31476888
257 + 31476631 = 31476888

Showing the first eight; more decompositions exist.
