Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72234, here are decompositions:

5 + 72229 = 72234
7 + 72227 = 72234
11 + 72223 = 72234
13 + 72221 = 72234
23 + 72211 = 72234
61 + 72173 = 72234
67 + 72167 = 72234
73 + 72161 = 72234

Showing the first eight; more decompositions exist.
