Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589622, here are decompositions:

11 + 31589611 = 31589622
61 + 31589561 = 31589622
83 + 31589539 = 31589622
109 + 31589513 = 31589622
139 + 31589483 = 31589622
149 + 31589473 = 31589622
199 + 31589423 = 31589622
263 + 31589359 = 31589622

Showing the first eight; more decompositions exist.
