Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722616, here are decompositions:

3 + 8722613 = 8722616
13 + 8722603 = 8722616
139 + 8722477 = 8722616
157 + 8722459 = 8722616
193 + 8722423 = 8722616
223 + 8722393 = 8722616
277 + 8722339 = 8722616
283 + 8722333 = 8722616

Showing the first eight; more decompositions exist.
