Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589022, here are decompositions:

5 + 31589017 = 31589022
11 + 31589011 = 31589022
29 + 31588993 = 31589022
43 + 31588979 = 31589022
71 + 31588951 = 31589022
79 + 31588943 = 31589022
89 + 31588933 = 31589022
313 + 31588709 = 31589022

Showing the first eight; more decompositions exist.
