Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463834, here are decompositions:

7 + 31463827 = 31463834
37 + 31463797 = 31463834
67 + 31463767 = 31463834
307 + 31463527 = 31463834
607 + 31463227 = 31463834
631 + 31463203 = 31463834
673 + 31463161 = 31463834
751 + 31463083 = 31463834

Showing the first eight; more decompositions exist.
