Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72436, here are decompositions:

5 + 72431 = 72436
53 + 72383 = 72436
83 + 72353 = 72436
149 + 72287 = 72436
167 + 72269 = 72436
263 + 72173 = 72436
269 + 72167 = 72436
347 + 72089 = 72436

Showing the first eight; more decompositions exist.
