Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700618, here are decompositions:

19 + 8700599 = 8700618
29 + 8700589 = 8700618
37 + 8700581 = 8700618
71 + 8700547 = 8700618
79 + 8700539 = 8700618
89 + 8700529 = 8700618
97 + 8700521 = 8700618
107 + 8700511 = 8700618

Showing the first eight; more decompositions exist.
