Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28210, here are decompositions:

29 + 28181 = 28210
47 + 28163 = 28210
59 + 28151 = 28210
101 + 28109 = 28210
113 + 28097 = 28210
179 + 28031 = 28210
191 + 28019 = 28210
227 + 27983 = 28210

Showing the first eight; more decompositions exist.
