Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542798, here are decompositions:

11 + 31542787 = 31542798
31 + 31542767 = 31542798
71 + 31542727 = 31542798
101 + 31542697 = 31542798
139 + 31542659 = 31542798
167 + 31542631 = 31542798
211 + 31542587 = 31542798
239 + 31542559 = 31542798

Showing the first eight; more decompositions exist.
