Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666246, here are decompositions:

73 + 8666173 = 8666246
79 + 8666167 = 8666246
109 + 8666137 = 8666246
223 + 8666023 = 8666246
229 + 8666017 = 8666246
307 + 8665939 = 8666246
313 + 8665933 = 8666246
349 + 8665897 = 8666246

Showing the first eight; more decompositions exist.
