Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659824, here are decompositions:

13 + 8659811 = 8659824
31 + 8659793 = 8659824
83 + 8659741 = 8659824
113 + 8659711 = 8659824
157 + 8659667 = 8659824
181 + 8659643 = 8659824
193 + 8659631 = 8659824
197 + 8659627 = 8659824

Showing the first eight; more decompositions exist.
