Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722450, here are decompositions:

3 + 8722447 = 8722450
41 + 8722409 = 8722450
59 + 8722391 = 8722450
83 + 8722367 = 8722450
89 + 8722361 = 8722450
167 + 8722283 = 8722450
227 + 8722223 = 8722450
239 + 8722211 = 8722450

Showing the first eight; more decompositions exist.
