Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707998, here are decompositions:

29 + 8707969 = 8707998
59 + 8707939 = 8707998
137 + 8707861 = 8707998
157 + 8707841 = 8707998
181 + 8707817 = 8707998
251 + 8707747 = 8707998
311 + 8707687 = 8707998
337 + 8707661 = 8707998

Showing the first eight; more decompositions exist.
