Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559496, here are decompositions:

29 + 31559467 = 31559496
53 + 31559443 = 31559496
79 + 31559417 = 31559496
83 + 31559413 = 31559496
113 + 31559383 = 31559496
179 + 31559317 = 31559496
233 + 31559263 = 31559496
257 + 31559239 = 31559496

Showing the first eight; more decompositions exist.
