Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72936, here are decompositions:

5 + 72931 = 72936
13 + 72923 = 72936
29 + 72907 = 72936
43 + 72893 = 72936
47 + 72889 = 72936
53 + 72883 = 72936
67 + 72869 = 72936
113 + 72823 = 72936

Showing the first eight; more decompositions exist.
