Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463754, here are decompositions:

11 + 31463743 = 31463754
37 + 31463717 = 31463754
41 + 31463713 = 31463754
73 + 31463681 = 31463754
163 + 31463591 = 31463754
167 + 31463587 = 31463754
227 + 31463527 = 31463754
271 + 31463483 = 31463754

Showing the first eight; more decompositions exist.
