Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66222, here are decompositions:

31 + 66191 = 66222
43 + 66179 = 66222
53 + 66169 = 66222
61 + 66161 = 66222
113 + 66109 = 66222
139 + 66083 = 66222
151 + 66071 = 66222
181 + 66041 = 66222

Showing the first eight; more decompositions exist.
