Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749144, here are decompositions:

3 + 8749141 = 8749144
11 + 8749133 = 8749144
17 + 8749127 = 8749144
23 + 8749121 = 8749144
137 + 8749007 = 8749144
191 + 8748953 = 8749144
251 + 8748893 = 8749144
263 + 8748881 = 8749144

Showing the first eight; more decompositions exist.
