Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589364, here are decompositions:

5 + 31589359 = 31589364
11 + 31589353 = 31589364
31 + 31589333 = 31589364
43 + 31589321 = 31589364
47 + 31589317 = 31589364
61 + 31589303 = 31589364
67 + 31589297 = 31589364
71 + 31589293 = 31589364

Showing the first eight; more decompositions exist.
