Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589304, here are decompositions:

7 + 31589297 = 31589304
11 + 31589293 = 31589304
13 + 31589291 = 31589304
17 + 31589287 = 31589304
53 + 31589251 = 31589304
107 + 31589197 = 31589304
137 + 31589167 = 31589304
167 + 31589137 = 31589304

Showing the first eight; more decompositions exist.
