Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717870, here are decompositions:

3 + 8717867 = 8717870
13 + 8717857 = 8717870
61 + 8717809 = 8717870
67 + 8717803 = 8717870
79 + 8717791 = 8717870
97 + 8717773 = 8717870
103 + 8717767 = 8717870
127 + 8717743 = 8717870

Showing the first eight; more decompositions exist.
