Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589436, here are decompositions:

13 + 31589423 = 31589436
29 + 31589407 = 31589436
59 + 31589377 = 31589436
83 + 31589353 = 31589436
97 + 31589339 = 31589436
103 + 31589333 = 31589436
107 + 31589329 = 31589436
139 + 31589297 = 31589436

Showing the first eight; more decompositions exist.
