Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72516, here are decompositions:

13 + 72503 = 72516
19 + 72497 = 72516
23 + 72493 = 72516
47 + 72469 = 72516
137 + 72379 = 72516
149 + 72367 = 72516
163 + 72353 = 72516
179 + 72337 = 72516

Showing the first eight; more decompositions exist.
