Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28402, here are decompositions:

53 + 28349 = 28402
83 + 28319 = 28402
113 + 28289 = 28402
173 + 28229 = 28402
191 + 28211 = 28402
239 + 28163 = 28402
251 + 28151 = 28402
293 + 28109 = 28402

Showing the first eight; more decompositions exist.
