Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529766, here are decompositions:

17 + 31529749 = 31529766
89 + 31529677 = 31529766
97 + 31529669 = 31529766
137 + 31529629 = 31529766
173 + 31529593 = 31529766
199 + 31529567 = 31529766
227 + 31529539 = 31529766
353 + 31529413 = 31529766

Showing the first eight; more decompositions exist.
