Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470486, here are decompositions:

17 + 31470469 = 31470486
43 + 31470443 = 31470486
107 + 31470379 = 31470486
127 + 31470359 = 31470486
149 + 31470337 = 31470486
163 + 31470323 = 31470486
193 + 31470293 = 31470486
227 + 31470259 = 31470486

Showing the first eight; more decompositions exist.
