Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42008, here are decompositions:

61 + 41947 = 42008
67 + 41941 = 42008
97 + 41911 = 42008
157 + 41851 = 42008
199 + 41809 = 42008
271 + 41737 = 42008
349 + 41659 = 42008
367 + 41641 = 42008

Showing the first eight; more decompositions exist.
