Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13068, here are decompositions:

5 + 13063 = 13068
19 + 13049 = 13068
31 + 13037 = 13068
59 + 13009 = 13068
61 + 13007 = 13068
67 + 13001 = 13068
89 + 12979 = 13068
101 + 12967 = 13068

Showing the first eight; more decompositions exist.
