Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57990, here are decompositions:

13 + 57977 = 57990
17 + 57973 = 57990
43 + 57947 = 57990
47 + 57943 = 57990
67 + 57923 = 57990
73 + 57917 = 57990
89 + 57901 = 57990
109 + 57881 = 57990

Showing the first eight; more decompositions exist.
