Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668860, here are decompositions:

23 + 8668837 = 8668860
29 + 8668831 = 8668860
43 + 8668817 = 8668860
47 + 8668813 = 8668860
59 + 8668801 = 8668860
61 + 8668799 = 8668860
97 + 8668763 = 8668860
139 + 8668721 = 8668860

Showing the first eight; more decompositions exist.
