Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470446, here are decompositions:

3 + 31470443 = 31470446
37 + 31470409 = 31470446
67 + 31470379 = 31470446
109 + 31470337 = 31470446
223 + 31470223 = 31470446
229 + 31470217 = 31470446
349 + 31470097 = 31470446
373 + 31470073 = 31470446

Showing the first eight; more decompositions exist.
