Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72918, here are decompositions:

7 + 72911 = 72918
11 + 72907 = 72918
17 + 72901 = 72918
29 + 72889 = 72918
47 + 72871 = 72918
59 + 72859 = 72918
101 + 72817 = 72918
151 + 72767 = 72918

Showing the first eight; more decompositions exist.
