Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566422, here are decompositions:

73 + 31566349 = 31566422
271 + 31566151 = 31566422
379 + 31566043 = 31566422
409 + 31566013 = 31566422
421 + 31566001 = 31566422
571 + 31565851 = 31566422
619 + 31565803 = 31566422
631 + 31565791 = 31566422

Showing the first eight; more decompositions exist.
