Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542422, here are decompositions:

3 + 31542419 = 31542422
31 + 31542391 = 31542422
193 + 31542229 = 31542422
409 + 31542013 = 31542422
421 + 31542001 = 31542422
433 + 31541989 = 31542422
523 + 31541899 = 31542422
661 + 31541761 = 31542422

Showing the first eight; more decompositions exist.
