Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700528, here are decompositions:

7 + 8700521 = 8700528
17 + 8700511 = 8700528
61 + 8700467 = 8700528
71 + 8700457 = 8700528
79 + 8700449 = 8700528
97 + 8700431 = 8700528
107 + 8700421 = 8700528
127 + 8700401 = 8700528

Showing the first eight; more decompositions exist.
