Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72486, here are decompositions:

5 + 72481 = 72486
17 + 72469 = 72486
19 + 72467 = 72486
103 + 72383 = 72486
107 + 72379 = 72486
149 + 72337 = 72486
173 + 72313 = 72486
179 + 72307 = 72486

Showing the first eight; more decompositions exist.
