Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589616, here are decompositions:

5 + 31589611 = 31589616
103 + 31589513 = 31589616
193 + 31589423 = 31589616
239 + 31589377 = 31589616
257 + 31589359 = 31589616
263 + 31589353 = 31589616
277 + 31589339 = 31589616
283 + 31589333 = 31589616

Showing the first eight; more decompositions exist.
