Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470836, here are decompositions:

3 + 31470833 = 31470836
13 + 31470823 = 31470836
37 + 31470799 = 31470836
43 + 31470793 = 31470836
127 + 31470709 = 31470836
367 + 31470469 = 31470836
457 + 31470379 = 31470836
499 + 31470337 = 31470836

Showing the first eight; more decompositions exist.
