Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12028, here are decompositions:

17 + 12011 = 12028
41 + 11987 = 12028
47 + 11981 = 12028
59 + 11969 = 12028
89 + 11939 = 12028
101 + 11927 = 12028
131 + 11897 = 12028
197 + 11831 = 12028

Showing the first eight; more decompositions exist.
