Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724678, here are decompositions:

29 + 8724649 = 8724678
37 + 8724641 = 8724678
47 + 8724631 = 8724678
59 + 8724619 = 8724678
89 + 8724589 = 8724678
167 + 8724511 = 8724678
181 + 8724497 = 8724678
191 + 8724487 = 8724678

Showing the first eight; more decompositions exist.
