Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690166, here are decompositions:

47 + 8690119 = 8690166
73 + 8690093 = 8690166
97 + 8690069 = 8690166
103 + 8690063 = 8690166
179 + 8689987 = 8690166
197 + 8689969 = 8690166
223 + 8689943 = 8690166
313 + 8689853 = 8690166

Showing the first eight; more decompositions exist.
