Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542826, here are decompositions:

17 + 31542809 = 31542826
59 + 31542767 = 31542826
149 + 31542677 = 31542826
167 + 31542659 = 31542826
239 + 31542587 = 31542826
317 + 31542509 = 31542826
347 + 31542479 = 31542826
389 + 31542437 = 31542826

Showing the first eight; more decompositions exist.
