Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72548, here are decompositions:

67 + 72481 = 72548
79 + 72469 = 72548
127 + 72421 = 72548
181 + 72367 = 72548
211 + 72337 = 72548
241 + 72307 = 72548
271 + 72277 = 72548
277 + 72271 = 72548

Showing the first eight; more decompositions exist.
