Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57450, here are decompositions:

23 + 57427 = 57450
37 + 57413 = 57450
53 + 57397 = 57450
61 + 57389 = 57450
67 + 57383 = 57450
83 + 57367 = 57450
101 + 57349 = 57450
103 + 57347 = 57450

Showing the first eight; more decompositions exist.
