Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700894, here are decompositions:

23 + 8700871 = 8700894
61 + 8700833 = 8700894
67 + 8700827 = 8700894
101 + 8700793 = 8700894
127 + 8700767 = 8700894
173 + 8700721 = 8700894
197 + 8700697 = 8700894
313 + 8700581 = 8700894

Showing the first eight; more decompositions exist.
