Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704240, here are decompositions:

11 + 8704229 = 8704240
47 + 8704193 = 8704240
71 + 8704169 = 8704240
173 + 8704067 = 8704240
191 + 8704049 = 8704240
269 + 8703971 = 8704240
521 + 8703719 = 8704240
599 + 8703641 = 8704240

Showing the first eight; more decompositions exist.
