Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720294, here are decompositions:

13 + 8720281 = 8720294
61 + 8720233 = 8720294
67 + 8720227 = 8720294
103 + 8720191 = 8720294
157 + 8720137 = 8720294
181 + 8720113 = 8720294
223 + 8720071 = 8720294
307 + 8719987 = 8720294

Showing the first eight; more decompositions exist.
