Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471214, here are decompositions:

7 + 31471207 = 31471214
43 + 31471171 = 31471214
67 + 31471147 = 31471214
163 + 31471051 = 31471214
223 + 31470991 = 31471214
367 + 31470847 = 31471214
421 + 31470793 = 31471214
433 + 31470781 = 31471214

Showing the first eight; more decompositions exist.
