Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621766, here are decompositions:

17 + 8621749 = 8621766
19 + 8621747 = 8621766
59 + 8621707 = 8621766
73 + 8621693 = 8621766
89 + 8621677 = 8621766
113 + 8621653 = 8621766
149 + 8621617 = 8621766
157 + 8621609 = 8621766

Showing the first eight; more decompositions exist.
