Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694870, here are decompositions:

13 + 8694857 = 8694870
29 + 8694841 = 8694870
31 + 8694839 = 8694870
47 + 8694823 = 8694870
73 + 8694797 = 8694870
103 + 8694767 = 8694870
131 + 8694739 = 8694870
137 + 8694733 = 8694870

Showing the first eight; more decompositions exist.
