Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57986, here are decompositions:

13 + 57973 = 57986
43 + 57943 = 57986
127 + 57859 = 57986
139 + 57847 = 57986
157 + 57829 = 57986
193 + 57793 = 57986
199 + 57787 = 57986
277 + 57709 = 57986

Showing the first eight; more decompositions exist.
