Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722384, here are decompositions:

17 + 8722367 = 8722384
23 + 8722361 = 8722384
53 + 8722331 = 8722384
101 + 8722283 = 8722384
173 + 8722211 = 8722384
191 + 8722193 = 8722384
197 + 8722187 = 8722384
383 + 8722001 = 8722384

Showing the first eight; more decompositions exist.
