Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457422, here are decompositions:

11 + 31457411 = 31457422
251 + 31457171 = 31457422
263 + 31457159 = 31457422
383 + 31457039 = 31457422
593 + 31456829 = 31457422
641 + 31456781 = 31457422
653 + 31456769 = 31457422
683 + 31456739 = 31457422

Showing the first eight; more decompositions exist.
