Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463486, here are decompositions:

3 + 31463483 = 31463486
79 + 31463407 = 31463486
97 + 31463389 = 31463486
157 + 31463329 = 31463486
283 + 31463203 = 31463486
349 + 31463137 = 31463486
409 + 31463077 = 31463486
463 + 31463023 = 31463486

Showing the first eight; more decompositions exist.
