Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655170, here are decompositions:

3 + 8655167 = 8655170
67 + 8655103 = 8655170
163 + 8655007 = 8655170
211 + 8654959 = 8655170
229 + 8654941 = 8655170
331 + 8654839 = 8655170
367 + 8654803 = 8655170
397 + 8654773 = 8655170

Showing the first eight; more decompositions exist.
