Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589768, here are decompositions:

31 + 31589737 = 31589768
37 + 31589731 = 31589768
61 + 31589707 = 31589768
109 + 31589659 = 31589768
157 + 31589611 = 31589768
229 + 31589539 = 31589768
307 + 31589461 = 31589768
367 + 31589401 = 31589768

Showing the first eight; more decompositions exist.
