Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645984, here are decompositions:

3 + 8645981 = 8645984
13 + 8645971 = 8645984
43 + 8645941 = 8645984
97 + 8645887 = 8645984
181 + 8645803 = 8645984
211 + 8645773 = 8645984
223 + 8645761 = 8645984
331 + 8645653 = 8645984

Showing the first eight; more decompositions exist.
