Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29220, here are decompositions:

11 + 29209 = 29220
13 + 29207 = 29220
19 + 29201 = 29220
29 + 29191 = 29220
41 + 29179 = 29220
47 + 29173 = 29220
53 + 29167 = 29220
67 + 29153 = 29220

Showing the first eight; more decompositions exist.
