Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655442, here are decompositions:

41 + 8655401 = 8655442
71 + 8655371 = 8655442
179 + 8655263 = 8655442
269 + 8655173 = 8655442
293 + 8655149 = 8655442
401 + 8655041 = 8655442
431 + 8655011 = 8655442
461 + 8654981 = 8655442

Showing the first eight; more decompositions exist.
