Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589350, here are decompositions:

11 + 31589339 = 31589350
17 + 31589333 = 31589350
29 + 31589321 = 31589350
47 + 31589303 = 31589350
53 + 31589297 = 31589350
59 + 31589291 = 31589350
167 + 31589183 = 31589350
251 + 31589099 = 31589350

Showing the first eight; more decompositions exist.
