Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463630, here are decompositions:

43 + 31463587 = 31463630
97 + 31463533 = 31463630
103 + 31463527 = 31463630
223 + 31463407 = 31463630
241 + 31463389 = 31463630
277 + 31463353 = 31463630
313 + 31463317 = 31463630
349 + 31463281 = 31463630

Showing the first eight; more decompositions exist.
