Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72560, here are decompositions:

13 + 72547 = 72560
67 + 72493 = 72560
79 + 72481 = 72560
139 + 72421 = 72560
181 + 72379 = 72560
193 + 72367 = 72560
223 + 72337 = 72560
283 + 72277 = 72560

Showing the first eight; more decompositions exist.
