Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483672, here are decompositions:

23 + 31483649 = 31483672
89 + 31483583 = 31483672
179 + 31483493 = 31483672
239 + 31483433 = 31483672
281 + 31483391 = 31483672
359 + 31483313 = 31483672
443 + 31483229 = 31483672
503 + 31483169 = 31483672

Showing the first eight; more decompositions exist.
