Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589484, here are decompositions:

11 + 31589473 = 31589484
23 + 31589461 = 31589484
61 + 31589423 = 31589484
83 + 31589401 = 31589484
107 + 31589377 = 31589484
131 + 31589353 = 31589484
151 + 31589333 = 31589484
163 + 31589321 = 31589484

Showing the first eight; more decompositions exist.
