Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72888, here are decompositions:

5 + 72883 = 72888
17 + 72871 = 72888
19 + 72869 = 72888
29 + 72859 = 72888
71 + 72817 = 72888
149 + 72739 = 72888
181 + 72707 = 72888
199 + 72689 = 72888

Showing the first eight; more decompositions exist.
