Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720244, here are decompositions:

11 + 8720233 = 8720244
17 + 8720227 = 8720244
53 + 8720191 = 8720244
67 + 8720177 = 8720244
73 + 8720171 = 8720244
83 + 8720161 = 8720244
107 + 8720137 = 8720244
131 + 8720113 = 8720244

Showing the first eight; more decompositions exist.
