Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722622, here are decompositions:

19 + 8722603 = 8722622
151 + 8722471 = 8722622
163 + 8722459 = 8722622
193 + 8722429 = 8722622
199 + 8722423 = 8722622
229 + 8722393 = 8722622
283 + 8722339 = 8722622
331 + 8722291 = 8722622

Showing the first eight; more decompositions exist.
