Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28102, here are decompositions:

3 + 28099 = 28102
5 + 28097 = 28102
71 + 28031 = 28102
83 + 28019 = 28102
101 + 28001 = 28102
149 + 27953 = 28102
251 + 27851 = 28102
293 + 27809 = 28102

Showing the first eight; more decompositions exist.
