Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720226, here are decompositions:

37 + 8720189 = 8720226
89 + 8720137 = 8720226
107 + 8720119 = 8720226
113 + 8720113 = 8720226
139 + 8720087 = 8720226
199 + 8720027 = 8720226
227 + 8719999 = 8720226
239 + 8719987 = 8720226

Showing the first eight; more decompositions exist.
