Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529896, here are decompositions:

5 + 31529891 = 31529896
53 + 31529843 = 31529896
113 + 31529783 = 31529896
179 + 31529717 = 31529896
227 + 31529669 = 31529896
389 + 31529507 = 31529896
449 + 31529447 = 31529896
617 + 31529279 = 31529896

Showing the first eight; more decompositions exist.
