Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57530, here are decompositions:

3 + 57527 = 57530
37 + 57493 = 57530
43 + 57487 = 57530
73 + 57457 = 57530
103 + 57427 = 57530
157 + 57373 = 57530
163 + 57367 = 57530
181 + 57349 = 57530

Showing the first eight; more decompositions exist.
