Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722262, here are decompositions:

139 + 8722123 = 8722262
163 + 8722099 = 8722262
181 + 8722081 = 8722262
229 + 8722033 = 8722262
349 + 8721913 = 8722262
379 + 8721883 = 8722262
499 + 8721763 = 8722262
631 + 8721631 = 8722262

Showing the first eight; more decompositions exist.
