Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559634, here are decompositions:

11 + 31559623 = 31559634
61 + 31559573 = 31559634
97 + 31559537 = 31559634
163 + 31559471 = 31559634
167 + 31559467 = 31559634
191 + 31559443 = 31559634
233 + 31559401 = 31559634
251 + 31559383 = 31559634

Showing the first eight; more decompositions exist.
