Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28162, here are decompositions:

11 + 28151 = 28162
53 + 28109 = 28162
131 + 28031 = 28162
179 + 27983 = 28162
269 + 27893 = 28162
311 + 27851 = 28162
353 + 27809 = 28162
359 + 27803 = 28162

Showing the first eight; more decompositions exist.
