Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82242, here are decompositions:

5 + 82237 = 82242
11 + 82231 = 82242
19 + 82223 = 82242
23 + 82219 = 82242
53 + 82189 = 82242
59 + 82183 = 82242
71 + 82171 = 82242
79 + 82163 = 82242

Showing the first eight; more decompositions exist.
