Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532892, here are decompositions:

11 + 31532881 = 31532892
19 + 31532873 = 31532892
29 + 31532863 = 31532892
59 + 31532833 = 31532892
199 + 31532693 = 31532892
233 + 31532659 = 31532892
239 + 31532653 = 31532892
311 + 31532581 = 31532892

Showing the first eight; more decompositions exist.
