Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749216, here are decompositions:

17 + 8749199 = 8749216
53 + 8749163 = 8749216
83 + 8749133 = 8749216
89 + 8749127 = 8749216
167 + 8749049 = 8749216
197 + 8749019 = 8749216
227 + 8748989 = 8749216
263 + 8748953 = 8749216

Showing the first eight; more decompositions exist.
