Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722686, here are decompositions:

13 + 8722673 = 8722686
43 + 8722643 = 8722686
73 + 8722613 = 8722686
79 + 8722607 = 8722686
83 + 8722603 = 8722686
227 + 8722459 = 8722686
239 + 8722447 = 8722686
257 + 8722429 = 8722686

Showing the first eight; more decompositions exist.
