Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655492, here are decompositions:

59 + 8655433 = 8655492
71 + 8655421 = 8655492
89 + 8655403 = 8655492
149 + 8655343 = 8655492
179 + 8655313 = 8655492
229 + 8655263 = 8655492
233 + 8655259 = 8655492
281 + 8655211 = 8655492

Showing the first eight; more decompositions exist.
