Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471422, here are decompositions:

11 + 31471411 = 31471422
61 + 31471361 = 31471422
251 + 31471171 = 31471422
313 + 31471109 = 31471422
331 + 31471091 = 31471422
379 + 31471043 = 31471422
421 + 31471001 = 31471422
431 + 31470991 = 31471422

Showing the first eight; more decompositions exist.
