Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463624, here are decompositions:

37 + 31463587 = 31463624
97 + 31463527 = 31463624
271 + 31463353 = 31463624
307 + 31463317 = 31463624
397 + 31463227 = 31463624
421 + 31463203 = 31463624
457 + 31463167 = 31463624
463 + 31463161 = 31463624

Showing the first eight; more decompositions exist.
