Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634212, here are decompositions:

43 + 8634169 = 8634212
73 + 8634139 = 8634212
79 + 8634133 = 8634212
163 + 8634049 = 8634212
229 + 8633983 = 8634212
241 + 8633971 = 8634212
271 + 8633941 = 8634212
313 + 8633899 = 8634212

Showing the first eight; more decompositions exist.
