Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749266, here are decompositions:

23 + 8749243 = 8749266
37 + 8749229 = 8749266
47 + 8749219 = 8749266
59 + 8749207 = 8749266
67 + 8749199 = 8749266
103 + 8749163 = 8749266
139 + 8749127 = 8749266
179 + 8749087 = 8749266

Showing the first eight; more decompositions exist.
