Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463252, here are decompositions:

3 + 31463249 = 31463252
229 + 31463023 = 31463252
283 + 31462969 = 31463252
421 + 31462831 = 31463252
523 + 31462729 = 31463252
643 + 31462609 = 31463252
661 + 31462591 = 31463252
673 + 31462579 = 31463252

Showing the first eight; more decompositions exist.
