Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666162, here are decompositions:

3 + 8666159 = 8666162
103 + 8666059 = 8666162
139 + 8666023 = 8666162
163 + 8665999 = 8666162
223 + 8665939 = 8666162
229 + 8665933 = 8666162
313 + 8665849 = 8666162
601 + 8665561 = 8666162

Showing the first eight; more decompositions exist.
