Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72740, here are decompositions:

7 + 72733 = 72740
13 + 72727 = 72740
61 + 72679 = 72740
67 + 72673 = 72740
79 + 72661 = 72740
97 + 72643 = 72740
127 + 72613 = 72740
163 + 72577 = 72740

Showing the first eight; more decompositions exist.
