Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28058, here are decompositions:

7 + 28051 = 28058
31 + 28027 = 28058
61 + 27997 = 28058
97 + 27961 = 28058
139 + 27919 = 28058
157 + 27901 = 28058
211 + 27847 = 28058
241 + 27817 = 28058

Showing the first eight; more decompositions exist.
