Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589966, here are decompositions:

13 + 31589953 = 31589966
43 + 31589923 = 31589966
97 + 31589869 = 31589966
139 + 31589827 = 31589966
193 + 31589773 = 31589966
229 + 31589737 = 31589966
283 + 31589683 = 31589966
307 + 31589659 = 31589966

Showing the first eight; more decompositions exist.
