Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72684, here are decompositions:

5 + 72679 = 72684
11 + 72673 = 72684
13 + 72671 = 72684
23 + 72661 = 72684
37 + 72647 = 72684
41 + 72643 = 72684
61 + 72623 = 72684
67 + 72617 = 72684

Showing the first eight; more decompositions exist.
