Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655490, here are decompositions:

89 + 8655401 = 8655490
227 + 8655263 = 8655490
293 + 8655197 = 8655490
317 + 8655173 = 8655490
419 + 8655071 = 8655490
443 + 8655047 = 8655490
449 + 8655041 = 8655490
461 + 8655029 = 8655490

Showing the first eight; more decompositions exist.
