Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707988, here are decompositions:

19 + 8707969 = 8707988
109 + 8707879 = 8707988
127 + 8707861 = 8707988
151 + 8707837 = 8707988
241 + 8707747 = 8707988
277 + 8707711 = 8707988
337 + 8707651 = 8707988
397 + 8707591 = 8707988

Showing the first eight; more decompositions exist.
