Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722162, here are decompositions:

83 + 8722079 = 8722162
173 + 8721989 = 8722162
233 + 8721929 = 8722162
311 + 8721851 = 8722162
389 + 8721773 = 8722162
461 + 8721701 = 8722162
563 + 8721599 = 8722162
719 + 8721443 = 8722162

Showing the first eight; more decompositions exist.
