Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463222, here are decompositions:

19 + 31463203 = 31463222
61 + 31463161 = 31463222
139 + 31463083 = 31463222
199 + 31463023 = 31463222
313 + 31462909 = 31463222
463 + 31462759 = 31463222
499 + 31462723 = 31463222
613 + 31462609 = 31463222

Showing the first eight; more decompositions exist.
