Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463516, here are decompositions:

109 + 31463407 = 31463516
127 + 31463389 = 31463516
163 + 31463353 = 31463516
199 + 31463317 = 31463516
313 + 31463203 = 31463516
349 + 31463167 = 31463516
379 + 31463137 = 31463516
433 + 31463083 = 31463516

Showing the first eight; more decompositions exist.
