Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655430, here are decompositions:

29 + 8655401 = 8655430
59 + 8655371 = 8655430
167 + 8655263 = 8655430
233 + 8655197 = 8655430
257 + 8655173 = 8655430
263 + 8655167 = 8655430
281 + 8655149 = 8655430
359 + 8655071 = 8655430

Showing the first eight; more decompositions exist.
