Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42006, here are decompositions:

7 + 41999 = 42006
23 + 41983 = 42006
37 + 41969 = 42006
47 + 41959 = 42006
53 + 41953 = 42006
59 + 41947 = 42006
79 + 41927 = 42006
103 + 41903 = 42006

Showing the first eight; more decompositions exist.
