Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655406, here are decompositions:

3 + 8655403 = 8655406
5 + 8655401 = 8655406
233 + 8655173 = 8655406
239 + 8655167 = 8655406
257 + 8655149 = 8655406
359 + 8655047 = 8655406
509 + 8654897 = 8655406
569 + 8654837 = 8655406

Showing the first eight; more decompositions exist.
