Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476960, here are decompositions:

13 + 31476947 = 31476960
29 + 31476931 = 31476960
43 + 31476917 = 31476960
79 + 31476881 = 31476960
89 + 31476871 = 31476960
107 + 31476853 = 31476960
113 + 31476847 = 31476960
131 + 31476829 = 31476960

Showing the first eight; more decompositions exist.
