Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542682, here are decompositions:

5 + 31542677 = 31542682
23 + 31542659 = 31542682
173 + 31542509 = 31542682
263 + 31542419 = 31542682
359 + 31542323 = 31542682
401 + 31542281 = 31542682
449 + 31542233 = 31542682
569 + 31542113 = 31542682

Showing the first eight; more decompositions exist.
