Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57100, here are decompositions:

3 + 57097 = 57100
11 + 57089 = 57100
23 + 57077 = 57100
41 + 57059 = 57100
53 + 57047 = 57100
59 + 57041 = 57100
101 + 56999 = 57100
107 + 56993 = 57100

Showing the first eight; more decompositions exist.
