Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722606, here are decompositions:

3 + 8722603 = 8722606
89 + 8722517 = 8722606
107 + 8722499 = 8722606
197 + 8722409 = 8722606
239 + 8722367 = 8722606
383 + 8722223 = 8722606
419 + 8722187 = 8722606
509 + 8722097 = 8722606

Showing the first eight; more decompositions exist.
