Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28030, here are decompositions:

3 + 28027 = 28030
11 + 28019 = 28030
29 + 28001 = 28030
47 + 27983 = 28030
83 + 27947 = 28030
89 + 27941 = 28030
113 + 27917 = 28030
137 + 27893 = 28030

Showing the first eight; more decompositions exist.
