Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700740, here are decompositions:

19 + 8700721 = 8700740
31 + 8700709 = 8700740
43 + 8700697 = 8700740
151 + 8700589 = 8700740
193 + 8700547 = 8700740
211 + 8700529 = 8700740
229 + 8700511 = 8700740
283 + 8700457 = 8700740

Showing the first eight; more decompositions exist.
