Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655516, here are decompositions:

19 + 8655497 = 8655516
59 + 8655457 = 8655516
83 + 8655433 = 8655516
113 + 8655403 = 8655516
167 + 8655349 = 8655516
173 + 8655343 = 8655516
229 + 8655287 = 8655516
257 + 8655259 = 8655516

Showing the first eight; more decompositions exist.
