Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660078, here are decompositions:

79 + 8659999 = 8660078
139 + 8659939 = 8660078
151 + 8659927 = 8660078
157 + 8659921 = 8660078
211 + 8659867 = 8660078
241 + 8659837 = 8660078
331 + 8659747 = 8660078
337 + 8659741 = 8660078

Showing the first eight; more decompositions exist.
