Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586026, here are decompositions:

23 + 31586003 = 31586026
29 + 31585997 = 31586026
47 + 31585979 = 31586026
53 + 31585973 = 31586026
89 + 31585937 = 31586026
137 + 31585889 = 31586026
359 + 31585667 = 31586026
389 + 31585637 = 31586026

Showing the first eight; more decompositions exist.
