Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655520, here are decompositions:

23 + 8655497 = 8655520
149 + 8655371 = 8655520
233 + 8655287 = 8655520
257 + 8655263 = 8655520
347 + 8655173 = 8655520
353 + 8655167 = 8655520
449 + 8655071 = 8655520
479 + 8655041 = 8655520

Showing the first eight; more decompositions exist.
