Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749270, here are decompositions:

41 + 8749229 = 8749270
71 + 8749199 = 8749270
107 + 8749163 = 8749270
137 + 8749133 = 8749270
149 + 8749121 = 8749270
251 + 8749019 = 8749270
263 + 8749007 = 8749270
269 + 8749001 = 8749270

Showing the first eight; more decompositions exist.
