Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72458, here are decompositions:

37 + 72421 = 72458
79 + 72379 = 72458
151 + 72307 = 72458
181 + 72277 = 72458
229 + 72229 = 72458
349 + 72109 = 72458
367 + 72091 = 72458
439 + 72019 = 72458

Showing the first eight; more decompositions exist.
