Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182238, here are decompositions:

5 + 182233 = 182238
29 + 182209 = 182238
37 + 182201 = 182238
59 + 182179 = 182238
61 + 182177 = 182238
71 + 182167 = 182238
79 + 182159 = 182238
97 + 182141 = 182238

Showing the first eight; more decompositions exist.
