Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542998, here are decompositions:

7 + 31542991 = 31542998
31 + 31542967 = 31542998
61 + 31542937 = 31542998
199 + 31542799 = 31542998
211 + 31542787 = 31542998
271 + 31542727 = 31542998
367 + 31542631 = 31542998
439 + 31542559 = 31542998

Showing the first eight; more decompositions exist.
