Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470576, here are decompositions:

13 + 31470563 = 31470576
19 + 31470557 = 31470576
29 + 31470547 = 31470576
107 + 31470469 = 31470576
167 + 31470409 = 31470576
197 + 31470379 = 31470576
223 + 31470353 = 31470576
239 + 31470337 = 31470576

Showing the first eight; more decompositions exist.
