Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702240, here are decompositions:

61 + 8702179 = 8702240
67 + 8702173 = 8702240
103 + 8702137 = 8702240
109 + 8702131 = 8702240
241 + 8701999 = 8702240
307 + 8701933 = 8702240
367 + 8701873 = 8702240
499 + 8701741 = 8702240

Showing the first eight; more decompositions exist.
