Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28112, here are decompositions:

3 + 28109 = 28112
13 + 28099 = 28112
31 + 28081 = 28112
43 + 28069 = 28112
61 + 28051 = 28112
151 + 27961 = 28112
193 + 27919 = 28112
211 + 27901 = 28112

Showing the first eight; more decompositions exist.
