Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463822, here are decompositions:

43 + 31463779 = 31463822
79 + 31463743 = 31463822
109 + 31463713 = 31463822
433 + 31463389 = 31463822
541 + 31463281 = 31463822
619 + 31463203 = 31463822
661 + 31463161 = 31463822
739 + 31463083 = 31463822

Showing the first eight; more decompositions exist.
