Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722066, here are decompositions:

47 + 8722019 = 8722066
137 + 8721929 = 8722066
149 + 8721917 = 8722066
293 + 8721773 = 8722066
317 + 8721749 = 8722066
449 + 8721617 = 8722066
467 + 8721599 = 8722066
593 + 8721473 = 8722066

Showing the first eight; more decompositions exist.
