Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722664, here are decompositions:

3 + 8722661 = 8722664
43 + 8722621 = 8722664
61 + 8722603 = 8722664
193 + 8722471 = 8722664
241 + 8722423 = 8722664
271 + 8722393 = 8722664
331 + 8722333 = 8722664
367 + 8722297 = 8722664

Showing the first eight; more decompositions exist.
