Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529892, here are decompositions:

11 + 31529881 = 31529892
73 + 31529819 = 31529892
109 + 31529783 = 31529892
211 + 31529681 = 31529892
223 + 31529669 = 31529892
241 + 31529651 = 31529892
263 + 31529629 = 31529892
269 + 31529623 = 31529892

Showing the first eight; more decompositions exist.
