Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463774, here are decompositions:

7 + 31463767 = 31463774
31 + 31463743 = 31463774
61 + 31463713 = 31463774
241 + 31463533 = 31463774
367 + 31463407 = 31463774
421 + 31463353 = 31463774
457 + 31463317 = 31463774
547 + 31463227 = 31463774

Showing the first eight; more decompositions exist.
