Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722922, here are decompositions:

31 + 8722891 = 8722922
211 + 8722711 = 8722922
463 + 8722459 = 8722922
499 + 8722423 = 8722922
619 + 8722303 = 8722922
631 + 8722291 = 8722922
751 + 8722171 = 8722922
823 + 8722099 = 8722922

Showing the first eight; more decompositions exist.
