Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749426, here are decompositions:

3 + 8749423 = 8749426
5 + 8749421 = 8749426
83 + 8749343 = 8749426
89 + 8749337 = 8749426
197 + 8749229 = 8749426
227 + 8749199 = 8749426
263 + 8749163 = 8749426
293 + 8749133 = 8749426

Showing the first eight; more decompositions exist.
