Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470456, here are decompositions:

13 + 31470443 = 31470456
47 + 31470409 = 31470456
97 + 31470359 = 31470456
103 + 31470353 = 31470456
163 + 31470293 = 31470456
197 + 31470259 = 31470456
233 + 31470223 = 31470456
239 + 31470217 = 31470456

Showing the first eight; more decompositions exist.
