Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57142, here are decompositions:

3 + 57139 = 57142
11 + 57131 = 57142
23 + 57119 = 57142
53 + 57089 = 57142
83 + 57059 = 57142
101 + 57041 = 57142
149 + 56993 = 57142
179 + 56963 = 57142

Showing the first eight; more decompositions exist.
