Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589560, here are decompositions:

47 + 31589513 = 31589560
137 + 31589423 = 31589560
227 + 31589333 = 31589560
239 + 31589321 = 31589560
257 + 31589303 = 31589560
263 + 31589297 = 31589560
269 + 31589291 = 31589560
461 + 31589099 = 31589560

Showing the first eight; more decompositions exist.
