Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470822, here are decompositions:

23 + 31470799 = 31470822
29 + 31470793 = 31470822
41 + 31470781 = 31470822
101 + 31470721 = 31470822
113 + 31470709 = 31470822
181 + 31470641 = 31470822
193 + 31470629 = 31470822
199 + 31470623 = 31470822

Showing the first eight; more decompositions exist.
