Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655500, here are decompositions:

3 + 8655497 = 8655500
43 + 8655457 = 8655500
67 + 8655433 = 8655500
79 + 8655421 = 8655500
97 + 8655403 = 8655500
151 + 8655349 = 8655500
157 + 8655343 = 8655500
193 + 8655307 = 8655500

Showing the first eight; more decompositions exist.
