Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66220, here are decompositions:

29 + 66191 = 66220
41 + 66179 = 66220
47 + 66173 = 66220
59 + 66161 = 66220
83 + 66137 = 66220
113 + 66107 = 66220
131 + 66089 = 66220
137 + 66083 = 66220

Showing the first eight; more decompositions exist.
