Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645924, here are decompositions:

37 + 8645887 = 8645924
61 + 8645863 = 8645924
151 + 8645773 = 8645924
163 + 8645761 = 8645924
271 + 8645653 = 8645924
277 + 8645647 = 8645924
307 + 8645617 = 8645924
337 + 8645587 = 8645924

Showing the first eight; more decompositions exist.
