Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546752, here are decompositions:

11 + 31546741 = 31546752
31 + 31546721 = 31546752
43 + 31546709 = 31546752
89 + 31546663 = 31546752
131 + 31546621 = 31546752
151 + 31546601 = 31546752
179 + 31546573 = 31546752
199 + 31546553 = 31546752

Showing the first eight; more decompositions exist.
