Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631864, here are decompositions:

13 + 8631851 = 8631864
41 + 8631823 = 8631864
61 + 8631803 = 8631864
83 + 8631781 = 8631864
127 + 8631737 = 8631864
151 + 8631713 = 8631864
191 + 8631673 = 8631864
331 + 8631533 = 8631864

Showing the first eight; more decompositions exist.
