Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72492, here are decompositions:

11 + 72481 = 72492
23 + 72469 = 72492
31 + 72461 = 72492
61 + 72431 = 72492
71 + 72421 = 72492
109 + 72383 = 72492
113 + 72379 = 72492
139 + 72353 = 72492

Showing the first eight; more decompositions exist.
