Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719216, here are decompositions:

3 + 8719213 = 8719216
5 + 8719211 = 8719216
17 + 8719199 = 8719216
29 + 8719187 = 8719216
53 + 8719163 = 8719216
83 + 8719133 = 8719216
89 + 8719127 = 8719216
167 + 8719049 = 8719216

Showing the first eight; more decompositions exist.
