Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589382, here are decompositions:

5 + 31589377 = 31589382
23 + 31589359 = 31589382
29 + 31589353 = 31589382
43 + 31589339 = 31589382
53 + 31589329 = 31589382
61 + 31589321 = 31589382
79 + 31589303 = 31589382
89 + 31589293 = 31589382

Showing the first eight; more decompositions exist.
