Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589528, here are decompositions:

67 + 31589461 = 31589528
127 + 31589401 = 31589528
151 + 31589377 = 31589528
199 + 31589329 = 31589528
211 + 31589317 = 31589528
241 + 31589287 = 31589528
277 + 31589251 = 31589528
331 + 31589197 = 31589528

Showing the first eight; more decompositions exist.
