Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700078, here are decompositions:

7 + 8700071 = 8700078
19 + 8700059 = 8700078
31 + 8700047 = 8700078
41 + 8700037 = 8700078
47 + 8700031 = 8700078
59 + 8700019 = 8700078
67 + 8700011 = 8700078
71 + 8700007 = 8700078

Showing the first eight; more decompositions exist.
