Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589694, here are decompositions:

11 + 31589683 = 31589694
61 + 31589633 = 31589694
83 + 31589611 = 31589694
127 + 31589567 = 31589694
181 + 31589513 = 31589694
211 + 31589483 = 31589694
233 + 31589461 = 31589694
271 + 31589423 = 31589694

Showing the first eight; more decompositions exist.
