Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42010, here are decompositions:

11 + 41999 = 42010
29 + 41981 = 42010
41 + 41969 = 42010
53 + 41957 = 42010
83 + 41927 = 42010
107 + 41903 = 42010
113 + 41897 = 42010
131 + 41879 = 42010

Showing the first eight; more decompositions exist.
