Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750920, here are decompositions:

29 + 8750891 = 8750920
47 + 8750873 = 8750920
53 + 8750867 = 8750920
89 + 8750831 = 8750920
137 + 8750783 = 8750920
149 + 8750771 = 8750920
263 + 8750657 = 8750920
281 + 8750639 = 8750920

Showing the first eight; more decompositions exist.
