Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57890, here are decompositions:

31 + 57859 = 57890
37 + 57853 = 57890
43 + 57847 = 57890
61 + 57829 = 57890
97 + 57793 = 57890
103 + 57787 = 57890
109 + 57781 = 57890
139 + 57751 = 57890

Showing the first eight; more decompositions exist.
