Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57480, here are decompositions:

13 + 57467 = 57480
23 + 57457 = 57480
53 + 57427 = 57480
67 + 57413 = 57480
83 + 57397 = 57480
97 + 57383 = 57480
107 + 57373 = 57480
113 + 57367 = 57480

Showing the first eight; more decompositions exist.
