Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71936, here are decompositions:

3 + 71933 = 71936
19 + 71917 = 71936
37 + 71899 = 71936
127 + 71809 = 71936
223 + 71713 = 71936
229 + 71707 = 71936
367 + 71569 = 71936
373 + 71563 = 71936

Showing the first eight; more decompositions exist.
