Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28222, here are decompositions:

3 + 28219 = 28222
11 + 28211 = 28222
41 + 28181 = 28222
59 + 28163 = 28222
71 + 28151 = 28222
113 + 28109 = 28222
191 + 28031 = 28222
239 + 27983 = 28222

Showing the first eight; more decompositions exist.
