Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655210, here are decompositions:

13 + 8655197 = 8655210
37 + 8655173 = 8655210
43 + 8655167 = 8655210
61 + 8655149 = 8655210
107 + 8655103 = 8655210
139 + 8655071 = 8655210
163 + 8655047 = 8655210
173 + 8655037 = 8655210

Showing the first eight; more decompositions exist.
