Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28032, here are decompositions:

5 + 28027 = 28032
13 + 28019 = 28032
31 + 28001 = 28032
71 + 27961 = 28032
79 + 27953 = 28032
89 + 27943 = 28032
113 + 27919 = 28032
131 + 27901 = 28032

Showing the first eight; more decompositions exist.
