Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722232, here are decompositions:

61 + 8722171 = 8722232
109 + 8722123 = 8722232
139 + 8722093 = 8722232
151 + 8722081 = 8722232
199 + 8722033 = 8722232
223 + 8722009 = 8722232
349 + 8721883 = 8722232
601 + 8721631 = 8722232

Showing the first eight; more decompositions exist.
