Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662216, here are decompositions:

29 + 8662187 = 8662216
47 + 8662169 = 8662216
83 + 8662133 = 8662216
89 + 8662127 = 8662216
107 + 8662109 = 8662216
137 + 8662079 = 8662216
179 + 8662037 = 8662216
197 + 8662019 = 8662216

Showing the first eight; more decompositions exist.
