Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471344, here are decompositions:

13 + 31471331 = 31471344
127 + 31471217 = 31471344
131 + 31471213 = 31471344
137 + 31471207 = 31471344
173 + 31471171 = 31471344
197 + 31471147 = 31471344
251 + 31471093 = 31471344
293 + 31471051 = 31471344

Showing the first eight; more decompositions exist.
