Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57872, here are decompositions:

13 + 57859 = 57872
19 + 57853 = 57872
43 + 57829 = 57872
79 + 57793 = 57872
163 + 57709 = 57872
193 + 57679 = 57872
223 + 57649 = 57872
271 + 57601 = 57872

Showing the first eight; more decompositions exist.
