Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726240, here are decompositions:

13 + 8726227 = 8726240
31 + 8726209 = 8726240
37 + 8726203 = 8726240
43 + 8726197 = 8726240
97 + 8726143 = 8726240
139 + 8726101 = 8726240
223 + 8726017 = 8726240
241 + 8725999 = 8726240

Showing the first eight; more decompositions exist.
