Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589610, here are decompositions:

43 + 31589567 = 31589610
71 + 31589539 = 31589610
97 + 31589513 = 31589610
127 + 31589483 = 31589610
137 + 31589473 = 31589610
149 + 31589461 = 31589610
233 + 31589377 = 31589610
251 + 31589359 = 31589610

Showing the first eight; more decompositions exist.
