Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72904, here are decompositions:

3 + 72901 = 72904
11 + 72893 = 72904
107 + 72797 = 72904
137 + 72767 = 72904
197 + 72707 = 72904
233 + 72671 = 72904
257 + 72647 = 72904
281 + 72623 = 72904

Showing the first eight; more decompositions exist.
