Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57220, here are decompositions:

17 + 57203 = 57220
29 + 57191 = 57220
41 + 57179 = 57220
47 + 57173 = 57220
71 + 57149 = 57220
89 + 57131 = 57220
101 + 57119 = 57220
113 + 57107 = 57220

Showing the first eight; more decompositions exist.
