Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661760, here are decompositions:

17 + 8661743 = 8661760
53 + 8661707 = 8661760
71 + 8661689 = 8661760
131 + 8661629 = 8661760
137 + 8661623 = 8661760
179 + 8661581 = 8661760
251 + 8661509 = 8661760
269 + 8661491 = 8661760

Showing the first eight; more decompositions exist.
