Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589670, here are decompositions:

11 + 31589659 = 31589670
37 + 31589633 = 31589670
59 + 31589611 = 31589670
103 + 31589567 = 31589670
109 + 31589561 = 31589670
131 + 31589539 = 31589670
157 + 31589513 = 31589670
197 + 31589473 = 31589670

Showing the first eight; more decompositions exist.
