Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722456, here are decompositions:

47 + 8722409 = 8722456
89 + 8722367 = 8722456
173 + 8722283 = 8722456
233 + 8722223 = 8722456
263 + 8722193 = 8722456
269 + 8722187 = 8722456
359 + 8722097 = 8722456
467 + 8721989 = 8722456

Showing the first eight; more decompositions exist.
