Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722144, here are decompositions:

47 + 8722097 = 8722144
227 + 8721917 = 8722144
293 + 8721851 = 8722144
443 + 8721701 = 8722144
677 + 8721467 = 8722144
701 + 8721443 = 8722144
773 + 8721371 = 8722144
863 + 8721281 = 8722144

Showing the first eight; more decompositions exist.
