Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749218, here are decompositions:

11 + 8749207 = 8749218
19 + 8749199 = 8749218
67 + 8749151 = 8749218
97 + 8749121 = 8749218
131 + 8749087 = 8749218
199 + 8749019 = 8749218
211 + 8749007 = 8749218
227 + 8748991 = 8749218

Showing the first eight; more decompositions exist.
