Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612166, here are decompositions:

47 + 8612119 = 8612166
67 + 8612099 = 8612166
107 + 8612059 = 8612166
109 + 8612057 = 8612166
127 + 8612039 = 8612166
179 + 8611987 = 8612166
197 + 8611969 = 8612166
263 + 8611903 = 8612166

Showing the first eight; more decompositions exist.
