Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72768, here are decompositions:

5 + 72763 = 72768
29 + 72739 = 72768
41 + 72727 = 72768
61 + 72707 = 72768
67 + 72701 = 72768
79 + 72689 = 72768
89 + 72679 = 72768
97 + 72671 = 72768

Showing the first eight; more decompositions exist.
