Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751000, here are decompositions:

31 + 8750969 = 8751000
43 + 8750957 = 8751000
53 + 8750947 = 8751000
59 + 8750941 = 8751000
67 + 8750933 = 8751000
79 + 8750921 = 8751000
107 + 8750893 = 8751000
109 + 8750891 = 8751000

Showing the first eight; more decompositions exist.
