Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655422, here are decompositions:

19 + 8655403 = 8655422
73 + 8655349 = 8655422
79 + 8655343 = 8655422
109 + 8655313 = 8655422
163 + 8655259 = 8655422
211 + 8655211 = 8655422
463 + 8654959 = 8655422
613 + 8654809 = 8655422

Showing the first eight; more decompositions exist.
