Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726670, here are decompositions:

23 + 8726647 = 8726670
37 + 8726633 = 8726670
59 + 8726611 = 8726670
83 + 8726587 = 8726670
97 + 8726573 = 8726670
101 + 8726569 = 8726670
137 + 8726533 = 8726670
149 + 8726521 = 8726670

Showing the first eight; more decompositions exist.
