Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668140, here are decompositions:

7 + 8668133 = 8668140
29 + 8668111 = 8668140
59 + 8668081 = 8668140
67 + 8668073 = 8668140
73 + 8668067 = 8668140
79 + 8668061 = 8668140
83 + 8668057 = 8668140
97 + 8668043 = 8668140

Showing the first eight; more decompositions exist.
