Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463732, here are decompositions:

19 + 31463713 = 31463732
43 + 31463689 = 31463732
199 + 31463533 = 31463732
379 + 31463353 = 31463732
463 + 31463269 = 31463732
571 + 31463161 = 31463732
709 + 31463023 = 31463732
823 + 31462909 = 31463732

Showing the first eight; more decompositions exist.
