Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529104, here are decompositions:

17 + 31529087 = 31529104
23 + 31529081 = 31529104
107 + 31528997 = 31529104
137 + 31528967 = 31529104
251 + 31528853 = 31529104
263 + 31528841 = 31529104
281 + 31528823 = 31529104
293 + 31528811 = 31529104

Showing the first eight; more decompositions exist.
