Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72484, here are decompositions:

3 + 72481 = 72484
17 + 72467 = 72484
23 + 72461 = 72484
53 + 72431 = 72484
101 + 72383 = 72484
131 + 72353 = 72484
197 + 72287 = 72484
233 + 72251 = 72484

Showing the first eight; more decompositions exist.
