Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642066, here are decompositions:

3 + 8642063 = 8642066
7 + 8642059 = 8642066
79 + 8641987 = 8642066
109 + 8641957 = 8642066
157 + 8641909 = 8642066
193 + 8641873 = 8642066
283 + 8641783 = 8642066
397 + 8641669 = 8642066

Showing the first eight; more decompositions exist.
