Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463684, here are decompositions:

3 + 31463681 = 31463684
97 + 31463587 = 31463684
151 + 31463533 = 31463684
157 + 31463527 = 31463684
277 + 31463407 = 31463684
331 + 31463353 = 31463684
367 + 31463317 = 31463684
457 + 31463227 = 31463684

Showing the first eight; more decompositions exist.
