Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2068, here are decompositions:

5 + 2063 = 2068
29 + 2039 = 2068
41 + 2027 = 2068
71 + 1997 = 2068
89 + 1979 = 2068
137 + 1931 = 2068
167 + 1901 = 2068
179 + 1889 = 2068

Showing the first eight; more decompositions exist.
