Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72536, here are decompositions:

3 + 72533 = 72536
43 + 72493 = 72536
67 + 72469 = 72536
157 + 72379 = 72536
199 + 72337 = 72536
223 + 72313 = 72536
229 + 72307 = 72536
283 + 72253 = 72536

Showing the first eight; more decompositions exist.
