Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476930, here are decompositions:

13 + 31476917 = 31476930
59 + 31476871 = 31476930
83 + 31476847 = 31476930
101 + 31476829 = 31476930
109 + 31476821 = 31476930
131 + 31476799 = 31476930
197 + 31476733 = 31476930
227 + 31476703 = 31476930

Showing the first eight; more decompositions exist.
