Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700440, here are decompositions:

19 + 8700421 = 8700440
79 + 8700361 = 8700440
157 + 8700283 = 8700440
271 + 8700169 = 8700440
409 + 8700031 = 8700440
421 + 8700019 = 8700440
433 + 8700007 = 8700440
439 + 8700001 = 8700440

Showing the first eight; more decompositions exist.
