Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722584, here are decompositions:

43 + 8722541 = 8722584
67 + 8722517 = 8722584
107 + 8722477 = 8722584
113 + 8722471 = 8722584
137 + 8722447 = 8722584
191 + 8722393 = 8722584
193 + 8722391 = 8722584
223 + 8722361 = 8722584

Showing the first eight; more decompositions exist.
