Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559376, here are decompositions:

5 + 31559371 = 31559376
59 + 31559317 = 31559376
113 + 31559263 = 31559376
137 + 31559239 = 31559376
157 + 31559219 = 31559376
227 + 31559149 = 31559376
283 + 31559093 = 31559376
307 + 31559069 = 31559376

Showing the first eight; more decompositions exist.
