Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542792, here are decompositions:

5 + 31542787 = 31542792
89 + 31542703 = 31542792
179 + 31542613 = 31542792
233 + 31542559 = 31542792
269 + 31542523 = 31542792
283 + 31542509 = 31542792
313 + 31542479 = 31542792
353 + 31542439 = 31542792

Showing the first eight; more decompositions exist.
