Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749366, here are decompositions:

23 + 8749343 = 8749366
29 + 8749337 = 8749366
137 + 8749229 = 8749366
167 + 8749199 = 8749366
233 + 8749133 = 8749366
239 + 8749127 = 8749366
317 + 8749049 = 8749366
347 + 8749019 = 8749366

Showing the first eight; more decompositions exist.
