Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756216, here are decompositions:

3 + 8756213 = 8756216
13 + 8756203 = 8756216
67 + 8756149 = 8756216
97 + 8756119 = 8756216
103 + 8756113 = 8756216
109 + 8756107 = 8756216
127 + 8756089 = 8756216
367 + 8755849 = 8756216

Showing the first eight; more decompositions exist.
