Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463942, here are decompositions:

31 + 31463911 = 31463942
163 + 31463779 = 31463942
199 + 31463743 = 31463942
229 + 31463713 = 31463942
409 + 31463533 = 31463942
613 + 31463329 = 31463942
661 + 31463281 = 31463942
673 + 31463269 = 31463942

Showing the first eight; more decompositions exist.
