Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655940, here are decompositions:

3 + 8655937 = 8655940
17 + 8655923 = 8655940
23 + 8655917 = 8655940
71 + 8655869 = 8655940
131 + 8655809 = 8655940
179 + 8655761 = 8655940
191 + 8655749 = 8655940
233 + 8655707 = 8655940

Showing the first eight; more decompositions exist.
