Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665228, here are decompositions:

71 + 8665157 = 8665228
197 + 8665031 = 8665228
251 + 8664977 = 8665228
269 + 8664959 = 8665228
281 + 8664947 = 8665228
359 + 8664869 = 8665228
557 + 8664671 = 8665228
647 + 8664581 = 8665228

Showing the first eight; more decompositions exist.
