Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589674, here are decompositions:

41 + 31589633 = 31589674
107 + 31589567 = 31589674
113 + 31589561 = 31589674
191 + 31589483 = 31589674
251 + 31589423 = 31589674
353 + 31589321 = 31589674
383 + 31589291 = 31589674
491 + 31589183 = 31589674

Showing the first eight; more decompositions exist.
