Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476120, here are decompositions:

7 + 31476113 = 31476120
23 + 31476097 = 31476120
47 + 31476073 = 31476120
61 + 31476059 = 31476120
89 + 31476031 = 31476120
103 + 31476017 = 31476120
107 + 31476013 = 31476120
157 + 31475963 = 31476120

Showing the first eight; more decompositions exist.
