Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589652, here are decompositions:

19 + 31589633 = 31589652
41 + 31589611 = 31589652
113 + 31589539 = 31589652
139 + 31589513 = 31589652
179 + 31589473 = 31589652
191 + 31589461 = 31589652
229 + 31589423 = 31589652
251 + 31589401 = 31589652

Showing the first eight; more decompositions exist.
