Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476222, here are decompositions:

53 + 31476169 = 31476222
73 + 31476149 = 31476222
79 + 31476143 = 31476222
103 + 31476119 = 31476222
109 + 31476113 = 31476222
149 + 31476073 = 31476222
163 + 31476059 = 31476222
191 + 31476031 = 31476222

Showing the first eight; more decompositions exist.
