Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589328, here are decompositions:

7 + 31589321 = 31589328
11 + 31589317 = 31589328
31 + 31589297 = 31589328
37 + 31589291 = 31589328
41 + 31589287 = 31589328
131 + 31589197 = 31589328
191 + 31589137 = 31589328
229 + 31589099 = 31589328

Showing the first eight; more decompositions exist.
