Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749230, here are decompositions:

11 + 8749219 = 8749230
23 + 8749207 = 8749230
31 + 8749199 = 8749230
67 + 8749163 = 8749230
79 + 8749151 = 8749230
89 + 8749141 = 8749230
97 + 8749133 = 8749230
103 + 8749127 = 8749230

Showing the first eight; more decompositions exist.
