Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655370, here are decompositions:

83 + 8655287 = 8655370
107 + 8655263 = 8655370
173 + 8655197 = 8655370
197 + 8655173 = 8655370
359 + 8655011 = 8655370
389 + 8654981 = 8655370
599 + 8654771 = 8655370
617 + 8654753 = 8655370

Showing the first eight; more decompositions exist.
