Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722514, here are decompositions:

37 + 8722477 = 8722514
43 + 8722471 = 8722514
67 + 8722447 = 8722514
181 + 8722333 = 8722514
211 + 8722303 = 8722514
223 + 8722291 = 8722514
277 + 8722237 = 8722514
397 + 8722117 = 8722514

Showing the first eight; more decompositions exist.
