Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589310, here are decompositions:

7 + 31589303 = 31589310
13 + 31589297 = 31589310
17 + 31589293 = 31589310
19 + 31589291 = 31589310
23 + 31589287 = 31589310
59 + 31589251 = 31589310
113 + 31589197 = 31589310
127 + 31589183 = 31589310

Showing the first eight; more decompositions exist.
