Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529496, here are decompositions:

17 + 31529479 = 31529496
83 + 31529413 = 31529496
137 + 31529359 = 31529496
149 + 31529347 = 31529496
223 + 31529273 = 31529496
227 + 31529269 = 31529496
239 + 31529257 = 31529496
277 + 31529219 = 31529496

Showing the first eight; more decompositions exist.
