Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646212, here are decompositions:

31 + 8646181 = 8646212
109 + 8646103 = 8646212
151 + 8646061 = 8646212
241 + 8645971 = 8646212
271 + 8645941 = 8646212
313 + 8645899 = 8646212
349 + 8645863 = 8646212
409 + 8645803 = 8646212

Showing the first eight; more decompositions exist.
