Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589646, here are decompositions:

13 + 31589633 = 31589646
79 + 31589567 = 31589646
107 + 31589539 = 31589646
163 + 31589483 = 31589646
173 + 31589473 = 31589646
223 + 31589423 = 31589646
239 + 31589407 = 31589646
269 + 31589377 = 31589646

Showing the first eight; more decompositions exist.
