Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589816, here are decompositions:

43 + 31589773 = 31589816
79 + 31589737 = 31589816
109 + 31589707 = 31589816
157 + 31589659 = 31589816
277 + 31589539 = 31589816
409 + 31589407 = 31589816
439 + 31589377 = 31589816
457 + 31589359 = 31589816

Showing the first eight; more decompositions exist.
