Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598850, here are decompositions:

11 + 31598839 = 31598850
61 + 31598789 = 31598850
67 + 31598783 = 31598850
71 + 31598779 = 31598850
79 + 31598771 = 31598850
97 + 31598753 = 31598850
149 + 31598701 = 31598850
163 + 31598687 = 31598850

Showing the first eight; more decompositions exist.
