Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476954, here are decompositions:

7 + 31476947 = 31476954
23 + 31476931 = 31476954
37 + 31476917 = 31476954
73 + 31476881 = 31476954
83 + 31476871 = 31476954
101 + 31476853 = 31476954
107 + 31476847 = 31476954
211 + 31476743 = 31476954

Showing the first eight; more decompositions exist.
