Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749240, here are decompositions:

11 + 8749229 = 8749240
41 + 8749199 = 8749240
89 + 8749151 = 8749240
107 + 8749133 = 8749240
113 + 8749127 = 8749240
191 + 8749049 = 8749240
233 + 8749007 = 8749240
239 + 8749001 = 8749240

Showing the first eight; more decompositions exist.
