Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720268, here are decompositions:

41 + 8720227 = 8720268
79 + 8720189 = 8720268
97 + 8720171 = 8720268
107 + 8720161 = 8720268
131 + 8720137 = 8720268
149 + 8720119 = 8720268
157 + 8720111 = 8720268
181 + 8720087 = 8720268

Showing the first eight; more decompositions exist.
