Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700670, here are decompositions:

71 + 8700599 = 8700670
89 + 8700581 = 8700670
107 + 8700563 = 8700670
131 + 8700539 = 8700670
149 + 8700521 = 8700670
197 + 8700473 = 8700670
239 + 8700431 = 8700670
263 + 8700407 = 8700670

Showing the first eight; more decompositions exist.
