Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722306, here are decompositions:

3 + 8722303 = 8722306
23 + 8722283 = 8722306
83 + 8722223 = 8722306
113 + 8722193 = 8722306
137 + 8722169 = 8722306
227 + 8722079 = 8722306
317 + 8721989 = 8722306
389 + 8721917 = 8722306

Showing the first eight; more decompositions exist.
