Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620066, here are decompositions:

3 + 8620063 = 8620066
17 + 8620049 = 8620066
23 + 8620043 = 8620066
173 + 8619893 = 8620066
197 + 8619869 = 8620066
269 + 8619797 = 8620066
293 + 8619773 = 8620066
347 + 8619719 = 8620066

Showing the first eight; more decompositions exist.
