Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589316, here are decompositions:

13 + 31589303 = 31589316
19 + 31589297 = 31589316
23 + 31589293 = 31589316
29 + 31589287 = 31589316
149 + 31589167 = 31589316
179 + 31589137 = 31589316
197 + 31589119 = 31589316
229 + 31589087 = 31589316

Showing the first eight; more decompositions exist.
