Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476156, here are decompositions:

7 + 31476149 = 31476156
13 + 31476143 = 31476156
37 + 31476119 = 31476156
43 + 31476113 = 31476156
59 + 31476097 = 31476156
83 + 31476073 = 31476156
97 + 31476059 = 31476156
139 + 31476017 = 31476156

Showing the first eight; more decompositions exist.
