Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463756, here are decompositions:

13 + 31463743 = 31463756
43 + 31463713 = 31463756
67 + 31463689 = 31463756
223 + 31463533 = 31463756
229 + 31463527 = 31463756
349 + 31463407 = 31463756
367 + 31463389 = 31463756
439 + 31463317 = 31463756

Showing the first eight; more decompositions exist.
