Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476216, here are decompositions:

29 + 31476187 = 31476216
47 + 31476169 = 31476216
59 + 31476157 = 31476216
67 + 31476149 = 31476216
73 + 31476143 = 31476216
97 + 31476119 = 31476216
103 + 31476113 = 31476216
157 + 31476059 = 31476216

Showing the first eight; more decompositions exist.
