Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722680, here are decompositions:

7 + 8722673 = 8722680
19 + 8722661 = 8722680
37 + 8722643 = 8722680
59 + 8722621 = 8722680
67 + 8722613 = 8722680
73 + 8722607 = 8722680
139 + 8722541 = 8722680
163 + 8722517 = 8722680

Showing the first eight; more decompositions exist.
