Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72884, here are decompositions:

13 + 72871 = 72884
61 + 72823 = 72884
67 + 72817 = 72884
151 + 72733 = 72884
157 + 72727 = 72884
211 + 72673 = 72884
223 + 72661 = 72884
241 + 72643 = 72884

Showing the first eight; more decompositions exist.
