Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476228, here are decompositions:

41 + 31476187 = 31476228
59 + 31476169 = 31476228
71 + 31476157 = 31476228
79 + 31476149 = 31476228
109 + 31476119 = 31476228
131 + 31476097 = 31476228
197 + 31476031 = 31476228
211 + 31476017 = 31476228

Showing the first eight; more decompositions exist.
