Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589362, here are decompositions:

3 + 31589359 = 31589362
23 + 31589339 = 31589362
29 + 31589333 = 31589362
41 + 31589321 = 31589362
59 + 31589303 = 31589362
71 + 31589291 = 31589362
179 + 31589183 = 31589362
263 + 31589099 = 31589362

Showing the first eight; more decompositions exist.
