Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72896, here are decompositions:

3 + 72893 = 72896
7 + 72889 = 72896
13 + 72883 = 72896
37 + 72859 = 72896
73 + 72823 = 72896
79 + 72817 = 72896
157 + 72739 = 72896
163 + 72733 = 72896

Showing the first eight; more decompositions exist.
