Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659740, here are decompositions:

29 + 8659711 = 8659740
71 + 8659669 = 8659740
73 + 8659667 = 8659740
97 + 8659643 = 8659740
109 + 8659631 = 8659740
113 + 8659627 = 8659740
139 + 8659601 = 8659740
151 + 8659589 = 8659740

Showing the first eight; more decompositions exist.
