Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589366, here are decompositions:

7 + 31589359 = 31589366
13 + 31589353 = 31589366
37 + 31589329 = 31589366
73 + 31589293 = 31589366
79 + 31589287 = 31589366
199 + 31589167 = 31589366
229 + 31589137 = 31589366
349 + 31589017 = 31589366

Showing the first eight; more decompositions exist.
