Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589536, here are decompositions:

23 + 31589513 = 31589536
53 + 31589483 = 31589536
113 + 31589423 = 31589536
197 + 31589339 = 31589536
233 + 31589303 = 31589536
239 + 31589297 = 31589536
353 + 31589183 = 31589536
449 + 31589087 = 31589536

Showing the first eight; more decompositions exist.
