Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470460, here are decompositions:

17 + 31470443 = 31470460
101 + 31470359 = 31470460
107 + 31470353 = 31470460
137 + 31470323 = 31470460
167 + 31470293 = 31470460
239 + 31470221 = 31470460
251 + 31470209 = 31470460
293 + 31470167 = 31470460

Showing the first eight; more decompositions exist.
