Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589356, here are decompositions:

3 + 31589353 = 31589356
17 + 31589339 = 31589356
23 + 31589333 = 31589356
53 + 31589303 = 31589356
59 + 31589297 = 31589356
173 + 31589183 = 31589356
257 + 31589099 = 31589356
269 + 31589087 = 31589356

Showing the first eight; more decompositions exist.
