Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72938, here are decompositions:

7 + 72931 = 72938
31 + 72907 = 72938
37 + 72901 = 72938
67 + 72871 = 72938
79 + 72859 = 72938
199 + 72739 = 72938
211 + 72727 = 72938
277 + 72661 = 72938

Showing the first eight; more decompositions exist.
