Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716642, here are decompositions:

3 + 8716639 = 8716642
23 + 8716619 = 8716642
29 + 8716613 = 8716642
59 + 8716583 = 8716642
89 + 8716553 = 8716642
173 + 8716469 = 8716642
191 + 8716451 = 8716642
269 + 8716373 = 8716642

Showing the first eight; more decompositions exist.
