Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655408, here are decompositions:

5 + 8655403 = 8655408
7 + 8655401 = 8655408
37 + 8655371 = 8655408
59 + 8655349 = 8655408
101 + 8655307 = 8655408
149 + 8655259 = 8655408
191 + 8655217 = 8655408
197 + 8655211 = 8655408

Showing the first eight; more decompositions exist.
