Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660154, here are decompositions:

47 + 8660107 = 8660154
67 + 8660087 = 8660154
73 + 8660081 = 8660154
101 + 8660053 = 8660154
103 + 8660051 = 8660154
157 + 8659997 = 8660154
197 + 8659957 = 8660154
227 + 8659927 = 8660154

Showing the first eight; more decompositions exist.
