Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501822, here are decompositions:

3 + 31501819 = 31501822
41 + 31501781 = 31501822
71 + 31501751 = 31501822
101 + 31501721 = 31501822
239 + 31501583 = 31501822
389 + 31501433 = 31501822
419 + 31501403 = 31501822
461 + 31501361 = 31501822

Showing the first eight; more decompositions exist.
