Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722536, here are decompositions:

19 + 8722517 = 8722536
37 + 8722499 = 8722536
59 + 8722477 = 8722536
89 + 8722447 = 8722536
107 + 8722429 = 8722536
113 + 8722423 = 8722536
127 + 8722409 = 8722536
197 + 8722339 = 8722536

Showing the first eight; more decompositions exist.
