Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589474, here are decompositions:

13 + 31589461 = 31589474
67 + 31589407 = 31589474
73 + 31589401 = 31589474
97 + 31589377 = 31589474
157 + 31589317 = 31589474
181 + 31589293 = 31589474
223 + 31589251 = 31589474
277 + 31589197 = 31589474

Showing the first eight; more decompositions exist.
