Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72898, here are decompositions:

5 + 72893 = 72898
29 + 72869 = 72898
101 + 72797 = 72898
131 + 72767 = 72898
179 + 72719 = 72898
191 + 72707 = 72898
197 + 72701 = 72898
227 + 72671 = 72898

Showing the first eight; more decompositions exist.
