Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722544, here are decompositions:

3 + 8722541 = 8722544
67 + 8722477 = 8722544
73 + 8722471 = 8722544
97 + 8722447 = 8722544
151 + 8722393 = 8722544
211 + 8722333 = 8722544
241 + 8722303 = 8722544
307 + 8722237 = 8722544

Showing the first eight; more decompositions exist.
