Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559594, here are decompositions:

127 + 31559467 = 31559594
151 + 31559443 = 31559594
181 + 31559413 = 31559594
193 + 31559401 = 31559594
211 + 31559383 = 31559594
223 + 31559371 = 31559594
277 + 31559317 = 31559594
331 + 31559263 = 31559594

Showing the first eight; more decompositions exist.
