Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463718, here are decompositions:

5 + 31463713 = 31463718
29 + 31463689 = 31463718
37 + 31463681 = 31463718
127 + 31463591 = 31463718
131 + 31463587 = 31463718
191 + 31463527 = 31463718
199 + 31463519 = 31463718
211 + 31463507 = 31463718

Showing the first eight; more decompositions exist.
