Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28072, here are decompositions:

3 + 28069 = 28072
41 + 28031 = 28072
53 + 28019 = 28072
71 + 28001 = 28072
89 + 27983 = 28072
131 + 27941 = 28072
179 + 27893 = 28072
263 + 27809 = 28072

Showing the first eight; more decompositions exist.
