Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589812, here are decompositions:

41 + 31589771 = 31589812
53 + 31589759 = 31589812
101 + 31589711 = 31589812
179 + 31589633 = 31589812
251 + 31589561 = 31589812
389 + 31589423 = 31589812
479 + 31589333 = 31589812
491 + 31589321 = 31589812

Showing the first eight; more decompositions exist.
