Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589782, here are decompositions:

5 + 31589777 = 31589782
11 + 31589771 = 31589782
23 + 31589759 = 31589782
71 + 31589711 = 31589782
89 + 31589693 = 31589782
149 + 31589633 = 31589782
269 + 31589513 = 31589782
359 + 31589423 = 31589782

Showing the first eight; more decompositions exist.
