Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589216, here are decompositions:

19 + 31589197 = 31589216
79 + 31589137 = 31589216
97 + 31589119 = 31589216
199 + 31589017 = 31589216
223 + 31588993 = 31589216
283 + 31588933 = 31589216
409 + 31588807 = 31589216
523 + 31588693 = 31589216

Showing the first eight; more decompositions exist.
