Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529092, here are decompositions:

3 + 31529089 = 31529092
5 + 31529087 = 31529092
11 + 31529081 = 31529092
239 + 31528853 = 31529092
251 + 31528841 = 31529092
269 + 31528823 = 31529092
281 + 31528811 = 31529092
479 + 31528613 = 31529092

Showing the first eight; more decompositions exist.
