Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750820, here are decompositions:

11 + 8750809 = 8750820
37 + 8750783 = 8750820
59 + 8750761 = 8750820
83 + 8750737 = 8750820
101 + 8750719 = 8750820
107 + 8750713 = 8750820
131 + 8750689 = 8750820
163 + 8750657 = 8750820

Showing the first eight; more decompositions exist.
