Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697870, here are decompositions:

11 + 8697859 = 8697870
19 + 8697851 = 8697870
37 + 8697833 = 8697870
47 + 8697823 = 8697870
59 + 8697811 = 8697870
61 + 8697809 = 8697870
67 + 8697803 = 8697870
73 + 8697797 = 8697870

Showing the first eight; more decompositions exist.
