Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543922, here are decompositions:

19 + 31543903 = 31543922
79 + 31543843 = 31543922
139 + 31543783 = 31543922
199 + 31543723 = 31543922
211 + 31543711 = 31543922
379 + 31543543 = 31543922
433 + 31543489 = 31543922
691 + 31543231 = 31543922

Showing the first eight; more decompositions exist.
