Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546732, here are decompositions:

11 + 31546721 = 31546732
23 + 31546709 = 31546732
71 + 31546661 = 31546732
131 + 31546601 = 31546732
149 + 31546583 = 31546732
179 + 31546553 = 31546732
263 + 31546469 = 31546732
281 + 31546451 = 31546732

Showing the first eight; more decompositions exist.
