Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655040, here are decompositions:

3 + 8655037 = 8655040
11 + 8655029 = 8655040
29 + 8655011 = 8655040
59 + 8654981 = 8655040
167 + 8654873 = 8655040
269 + 8654771 = 8655040
281 + 8654759 = 8655040
311 + 8654729 = 8655040

Showing the first eight; more decompositions exist.
