Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3072, here are decompositions:

5 + 3067 = 3072
11 + 3061 = 3072
23 + 3049 = 3072
31 + 3041 = 3072
53 + 3019 = 3072
61 + 3011 = 3072
71 + 3001 = 3072
73 + 2999 = 3072

Showing the first eight; more decompositions exist.
