Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589572, here are decompositions:

5 + 31589567 = 31589572
11 + 31589561 = 31589572
59 + 31589513 = 31589572
89 + 31589483 = 31589572
149 + 31589423 = 31589572
233 + 31589339 = 31589572
239 + 31589333 = 31589572
251 + 31589321 = 31589572

Showing the first eight; more decompositions exist.
