Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72804, here are decompositions:

7 + 72797 = 72804
37 + 72767 = 72804
41 + 72763 = 72804
71 + 72733 = 72804
97 + 72707 = 72804
103 + 72701 = 72804
131 + 72673 = 72804
157 + 72647 = 72804

Showing the first eight; more decompositions exist.
