Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567328, here are decompositions:

31 + 31567297 = 31567328
61 + 31567267 = 31567328
97 + 31567231 = 31567328
109 + 31567219 = 31567328
241 + 31567087 = 31567328
349 + 31566979 = 31567328
409 + 31566919 = 31567328
619 + 31566709 = 31567328

Showing the first eight; more decompositions exist.
