Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654212, here are decompositions:

11 + 8654201 = 8654212
29 + 8654183 = 8654212
41 + 8654171 = 8654212
89 + 8654123 = 8654212
101 + 8654111 = 8654212
113 + 8654099 = 8654212
173 + 8654039 = 8654212
179 + 8654033 = 8654212

Showing the first eight; more decompositions exist.
