Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589526, here are decompositions:

13 + 31589513 = 31589526
43 + 31589483 = 31589526
53 + 31589473 = 31589526
103 + 31589423 = 31589526
149 + 31589377 = 31589526
167 + 31589359 = 31589526
173 + 31589353 = 31589526
193 + 31589333 = 31589526

Showing the first eight; more decompositions exist.
