Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57258, here are decompositions:

7 + 57251 = 57258
17 + 57241 = 57258
37 + 57221 = 57258
67 + 57191 = 57258
79 + 57179 = 57258
109 + 57149 = 57258
127 + 57131 = 57258
139 + 57119 = 57258

Showing the first eight; more decompositions exist.
