Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542708, here are decompositions:

5 + 31542703 = 31542708
11 + 31542697 = 31542708
31 + 31542677 = 31542708
149 + 31542559 = 31542708
199 + 31542509 = 31542708
229 + 31542479 = 31542708
251 + 31542457 = 31542708
269 + 31542439 = 31542708

Showing the first eight; more decompositions exist.
