Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471274, here are decompositions:

61 + 31471213 = 31471274
67 + 31471207 = 31471274
103 + 31471171 = 31471274
127 + 31471147 = 31471274
151 + 31471123 = 31471274
181 + 31471093 = 31471274
223 + 31471051 = 31471274
277 + 31470997 = 31471274

Showing the first eight; more decompositions exist.
