Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72738, here are decompositions:

5 + 72733 = 72738
11 + 72727 = 72738
19 + 72719 = 72738
31 + 72707 = 72738
37 + 72701 = 72738
59 + 72679 = 72738
67 + 72671 = 72738
89 + 72649 = 72738

Showing the first eight; more decompositions exist.
