Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656040, here are decompositions:

7 + 8656033 = 8656040
73 + 8655967 = 8656040
103 + 8655937 = 8656040
139 + 8655901 = 8656040
157 + 8655883 = 8656040
163 + 8655877 = 8656040
181 + 8655859 = 8656040
199 + 8655841 = 8656040

Showing the first eight; more decompositions exist.
