Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749404, here are decompositions:

47 + 8749357 = 8749404
61 + 8749343 = 8749404
67 + 8749337 = 8749404
73 + 8749331 = 8749404
197 + 8749207 = 8749404
241 + 8749163 = 8749404
263 + 8749141 = 8749404
271 + 8749133 = 8749404

Showing the first eight; more decompositions exist.
