Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722736, here are decompositions:

277 + 8722459 = 8722736
307 + 8722429 = 8722736
313 + 8722423 = 8722736
397 + 8722339 = 8722736
433 + 8722303 = 8722736
439 + 8722297 = 8722736
499 + 8722237 = 8722736
613 + 8722123 = 8722736

Showing the first eight; more decompositions exist.
