Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589864, here are decompositions:

3 + 31589861 = 31589864
37 + 31589827 = 31589864
127 + 31589737 = 31589864
157 + 31589707 = 31589864
181 + 31589683 = 31589864
457 + 31589407 = 31589864
463 + 31589401 = 31589864
487 + 31589377 = 31589864

Showing the first eight; more decompositions exist.
