Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666236, here are decompositions:

17 + 8666219 = 8666236
53 + 8666183 = 8666236
83 + 8666153 = 8666236
167 + 8666069 = 8666236
179 + 8666057 = 8666236
263 + 8665973 = 8666236
269 + 8665967 = 8666236
347 + 8665889 = 8666236

Showing the first eight; more decompositions exist.
