Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589486, here are decompositions:

3 + 31589483 = 31589486
13 + 31589473 = 31589486
79 + 31589407 = 31589486
109 + 31589377 = 31589486
127 + 31589359 = 31589486
157 + 31589329 = 31589486
193 + 31589293 = 31589486
199 + 31589287 = 31589486

Showing the first eight; more decompositions exist.
