Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722610, here are decompositions:

3 + 8722607 = 8722610
7 + 8722603 = 8722610
139 + 8722471 = 8722610
151 + 8722459 = 8722610
163 + 8722447 = 8722610
181 + 8722429 = 8722610
271 + 8722339 = 8722610
277 + 8722333 = 8722610

Showing the first eight; more decompositions exist.
