Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655424, here are decompositions:

3 + 8655421 = 8655424
23 + 8655401 = 8655424
53 + 8655371 = 8655424
137 + 8655287 = 8655424
227 + 8655197 = 8655424
251 + 8655173 = 8655424
257 + 8655167 = 8655424
353 + 8655071 = 8655424

Showing the first eight; more decompositions exist.
