Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620222, here are decompositions:

3 + 8620219 = 8620222
5 + 8620217 = 8620222
11 + 8620211 = 8620222
71 + 8620151 = 8620222
89 + 8620133 = 8620222
101 + 8620121 = 8620222
113 + 8620109 = 8620222
173 + 8620049 = 8620222

Showing the first eight; more decompositions exist.
