Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644212, here are decompositions:

41 + 8644171 = 8644212
89 + 8644123 = 8644212
131 + 8644081 = 8644212
151 + 8644061 = 8644212
163 + 8644049 = 8644212
193 + 8644019 = 8644212
271 + 8643941 = 8644212
293 + 8643919 = 8644212

Showing the first eight; more decompositions exist.
