Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589570, here are decompositions:

3 + 31589567 = 31589570
31 + 31589539 = 31589570
97 + 31589473 = 31589570
109 + 31589461 = 31589570
163 + 31589407 = 31589570
193 + 31589377 = 31589570
211 + 31589359 = 31589570
241 + 31589329 = 31589570

Showing the first eight; more decompositions exist.
