Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589122, here are decompositions:

3 + 31589119 = 31589122
23 + 31589099 = 31589122
53 + 31589069 = 31589122
179 + 31588943 = 31589122
443 + 31588679 = 31589122
449 + 31588673 = 31589122
479 + 31588643 = 31589122
491 + 31588631 = 31589122

Showing the first eight; more decompositions exist.
