Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28932, here are decompositions:

5 + 28927 = 28932
11 + 28921 = 28932
23 + 28909 = 28932
31 + 28901 = 28932
53 + 28879 = 28932
61 + 28871 = 28932
73 + 28859 = 28932
89 + 28843 = 28932

Showing the first eight; more decompositions exist.
