Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641066, here are decompositions:

3 + 8641063 = 8641066
59 + 8641007 = 8641066
89 + 8640977 = 8641066
179 + 8640887 = 8641066
347 + 8640719 = 8641066
353 + 8640713 = 8641066
359 + 8640707 = 8641066
383 + 8640683 = 8641066

Showing the first eight; more decompositions exist.
