Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722064, here are decompositions:

31 + 8722033 = 8722064
37 + 8722027 = 8722064
67 + 8721997 = 8722064
151 + 8721913 = 8722064
157 + 8721907 = 8722064
181 + 8721883 = 8722064
397 + 8721667 = 8722064
433 + 8721631 = 8722064

Showing the first eight; more decompositions exist.
