Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666306, here are decompositions:

37 + 8666269 = 8666306
139 + 8666167 = 8666306
283 + 8666023 = 8666306
307 + 8665999 = 8666306
367 + 8665939 = 8666306
373 + 8665933 = 8666306
409 + 8665897 = 8666306
433 + 8665873 = 8666306

Showing the first eight; more decompositions exist.
