Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620216, here are decompositions:

5 + 8620211 = 8620216
29 + 8620187 = 8620216
83 + 8620133 = 8620216
107 + 8620109 = 8620216
167 + 8620049 = 8620216
173 + 8620043 = 8620216
347 + 8619869 = 8620216
359 + 8619857 = 8620216

Showing the first eight; more decompositions exist.
