Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559474, here are decompositions:

3 + 31559471 = 31559474
7 + 31559467 = 31559474
31 + 31559443 = 31559474
61 + 31559413 = 31559474
73 + 31559401 = 31559474
103 + 31559371 = 31559474
157 + 31559317 = 31559474
211 + 31559263 = 31559474

Showing the first eight; more decompositions exist.
