Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720274, here are decompositions:

41 + 8720233 = 8720274
47 + 8720227 = 8720274
83 + 8720191 = 8720274
97 + 8720177 = 8720274
103 + 8720171 = 8720274
113 + 8720161 = 8720274
137 + 8720137 = 8720274
163 + 8720111 = 8720274

Showing the first eight; more decompositions exist.
