Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589716, here are decompositions:

5 + 31589711 = 31589716
23 + 31589693 = 31589716
83 + 31589633 = 31589716
149 + 31589567 = 31589716
233 + 31589483 = 31589716
293 + 31589423 = 31589716
383 + 31589333 = 31589716
419 + 31589297 = 31589716

Showing the first eight; more decompositions exist.
