Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736216, here are decompositions:

7 + 8736209 = 8736216
17 + 8736199 = 8736216
29 + 8736187 = 8736216
37 + 8736179 = 8736216
43 + 8736173 = 8736216
89 + 8736127 = 8736216
107 + 8736109 = 8736216
127 + 8736089 = 8736216

Showing the first eight; more decompositions exist.
