Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471182, here are decompositions:

11 + 31471171 = 31471182
59 + 31471123 = 31471182
73 + 31471109 = 31471182
89 + 31471093 = 31471182
103 + 31471079 = 31471182
131 + 31471051 = 31471182
139 + 31471043 = 31471182
151 + 31471031 = 31471182

Showing the first eight; more decompositions exist.
