Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670166, here are decompositions:

59 + 8670107 = 8670166
137 + 8670029 = 8670166
173 + 8669993 = 8670166
227 + 8669939 = 8670166
269 + 8669897 = 8670166
389 + 8669777 = 8670166
509 + 8669657 = 8670166
653 + 8669513 = 8670166

Showing the first eight; more decompositions exist.
