Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72392, here are decompositions:

13 + 72379 = 72392
79 + 72313 = 72392
139 + 72253 = 72392
163 + 72229 = 72392
181 + 72211 = 72392
223 + 72169 = 72392
283 + 72109 = 72392
349 + 72043 = 72392

Showing the first eight; more decompositions exist.
