Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589466, here are decompositions:

5 + 31589461 = 31589466
43 + 31589423 = 31589466
59 + 31589407 = 31589466
89 + 31589377 = 31589466
107 + 31589359 = 31589466
113 + 31589353 = 31589466
127 + 31589339 = 31589466
137 + 31589329 = 31589466

Showing the first eight; more decompositions exist.
