Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589788, here are decompositions:

11 + 31589777 = 31589788
17 + 31589771 = 31589788
29 + 31589759 = 31589788
227 + 31589561 = 31589788
449 + 31589339 = 31589788
467 + 31589321 = 31589788
491 + 31589297 = 31589788
701 + 31589087 = 31589788

Showing the first eight; more decompositions exist.
