Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476186, here are decompositions:

17 + 31476169 = 31476186
29 + 31476157 = 31476186
37 + 31476149 = 31476186
43 + 31476143 = 31476186
67 + 31476119 = 31476186
73 + 31476113 = 31476186
89 + 31476097 = 31476186
113 + 31476073 = 31476186

Showing the first eight; more decompositions exist.
