Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700066, here are decompositions:

7 + 8700059 = 8700066
19 + 8700047 = 8700066
29 + 8700037 = 8700066
47 + 8700019 = 8700066
59 + 8700007 = 8700066
73 + 8699993 = 8700066
97 + 8699969 = 8700066
107 + 8699959 = 8700066

Showing the first eight; more decompositions exist.
