Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700012, here are decompositions:

5 + 8700007 = 8700012
11 + 8700001 = 8700012
19 + 8699993 = 8700012
31 + 8699981 = 8700012
43 + 8699969 = 8700012
53 + 8699959 = 8700012
59 + 8699953 = 8700012
89 + 8699923 = 8700012

Showing the first eight; more decompositions exist.
