Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659782, here are decompositions:

13 + 8659769 = 8659782
41 + 8659741 = 8659782
71 + 8659711 = 8659782
113 + 8659669 = 8659782
139 + 8659643 = 8659782
151 + 8659631 = 8659782
181 + 8659601 = 8659782
193 + 8659589 = 8659782

Showing the first eight; more decompositions exist.
