Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662222, here are decompositions:

3 + 8662219 = 8662222
5 + 8662217 = 8662222
53 + 8662169 = 8662222
71 + 8662151 = 8662222
89 + 8662133 = 8662222
113 + 8662109 = 8662222
131 + 8662091 = 8662222
269 + 8661953 = 8662222

Showing the first eight; more decompositions exist.
