Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546832, here are decompositions:

19 + 31546813 = 31546832
43 + 31546789 = 31546832
73 + 31546759 = 31546832
199 + 31546633 = 31546832
211 + 31546621 = 31546832
241 + 31546591 = 31546832
349 + 31546483 = 31546832
439 + 31546393 = 31546832

Showing the first eight; more decompositions exist.
