Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589936, here are decompositions:

13 + 31589923 = 31589936
67 + 31589869 = 31589936
109 + 31589827 = 31589936
163 + 31589773 = 31589936
199 + 31589737 = 31589936
229 + 31589707 = 31589936
277 + 31589659 = 31589936
397 + 31589539 = 31589936

Showing the first eight; more decompositions exist.
