Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707928, here are decompositions:

67 + 8707861 = 8707928
181 + 8707747 = 8707928
241 + 8707687 = 8707928
277 + 8707651 = 8707928
337 + 8707591 = 8707928
349 + 8707579 = 8707928
499 + 8707429 = 8707928
571 + 8707357 = 8707928

Showing the first eight; more decompositions exist.
