Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72496, here are decompositions:

3 + 72493 = 72496
29 + 72467 = 72496
113 + 72383 = 72496
227 + 72269 = 72496
269 + 72227 = 72496
419 + 72077 = 72496
443 + 72053 = 72496
449 + 72047 = 72496

Showing the first eight; more decompositions exist.
