Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700518, here are decompositions:

7 + 8700511 = 8700518
61 + 8700457 = 8700518
97 + 8700421 = 8700518
157 + 8700361 = 8700518
349 + 8700169 = 8700518
397 + 8700121 = 8700518
439 + 8700079 = 8700518
487 + 8700031 = 8700518

Showing the first eight; more decompositions exist.
