Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722386, here are decompositions:

19 + 8722367 = 8722386
47 + 8722339 = 8722386
53 + 8722333 = 8722386
83 + 8722303 = 8722386
89 + 8722297 = 8722386
103 + 8722283 = 8722386
149 + 8722237 = 8722386
163 + 8722223 = 8722386

Showing the first eight; more decompositions exist.
