Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57210, here are decompositions:

7 + 57203 = 57210
17 + 57193 = 57210
19 + 57191 = 57210
31 + 57179 = 57210
37 + 57173 = 57210
47 + 57163 = 57210
61 + 57149 = 57210
67 + 57143 = 57210

Showing the first eight; more decompositions exist.
