Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722156, here are decompositions:

59 + 8722097 = 8722156
137 + 8722019 = 8722156
167 + 8721989 = 8722156
227 + 8721929 = 8722156
239 + 8721917 = 8722156
383 + 8721773 = 8722156
419 + 8721737 = 8722156
557 + 8721599 = 8722156

Showing the first eight; more decompositions exist.
