Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751232, here are decompositions:

11 + 8751221 = 8751232
59 + 8751173 = 8751232
89 + 8751143 = 8751232
131 + 8751101 = 8751232
263 + 8750969 = 8751232
311 + 8750921 = 8751232
359 + 8750873 = 8751232
389 + 8750843 = 8751232

Showing the first eight; more decompositions exist.
