Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700870, here are decompositions:

37 + 8700833 = 8700870
43 + 8700827 = 8700870
53 + 8700817 = 8700870
71 + 8700799 = 8700870
97 + 8700773 = 8700870
103 + 8700767 = 8700870
149 + 8700721 = 8700870
173 + 8700697 = 8700870

Showing the first eight; more decompositions exist.
