Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722516, here are decompositions:

17 + 8722499 = 8722516
107 + 8722409 = 8722516
149 + 8722367 = 8722516
233 + 8722283 = 8722516
293 + 8722223 = 8722516
347 + 8722169 = 8722516
419 + 8722097 = 8722516
587 + 8721929 = 8722516

Showing the first eight; more decompositions exist.
