Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463748, here are decompositions:

5 + 31463743 = 31463748
31 + 31463717 = 31463748
59 + 31463689 = 31463748
67 + 31463681 = 31463748
157 + 31463591 = 31463748
229 + 31463519 = 31463748
241 + 31463507 = 31463748
271 + 31463477 = 31463748

Showing the first eight; more decompositions exist.
