Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655374, here are decompositions:

3 + 8655371 = 8655374
31 + 8655343 = 8655374
43 + 8655331 = 8655374
61 + 8655313 = 8655374
67 + 8655307 = 8655374
157 + 8655217 = 8655374
163 + 8655211 = 8655374
271 + 8655103 = 8655374

Showing the first eight; more decompositions exist.
