Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589334, here are decompositions:

5 + 31589329 = 31589334
13 + 31589321 = 31589334
17 + 31589317 = 31589334
31 + 31589303 = 31589334
37 + 31589297 = 31589334
41 + 31589293 = 31589334
43 + 31589291 = 31589334
47 + 31589287 = 31589334

Showing the first eight; more decompositions exist.
