Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670864, here are decompositions:

53 + 8670811 = 8670864
73 + 8670791 = 8670864
113 + 8670751 = 8670864
151 + 8670713 = 8670864
197 + 8670667 = 8670864
211 + 8670653 = 8670864
227 + 8670637 = 8670864
281 + 8670583 = 8670864

Showing the first eight; more decompositions exist.
