Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751028, here are decompositions:

59 + 8750969 = 8751028
71 + 8750957 = 8751028
107 + 8750921 = 8751028
137 + 8750891 = 8751028
197 + 8750831 = 8751028
257 + 8750771 = 8751028
389 + 8750639 = 8751028
479 + 8750549 = 8751028

Showing the first eight; more decompositions exist.
