Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72584, here are decompositions:

7 + 72577 = 72584
37 + 72547 = 72584
103 + 72481 = 72584
163 + 72421 = 72584
271 + 72313 = 72584
277 + 72307 = 72584
307 + 72277 = 72584
313 + 72271 = 72584

Showing the first eight; more decompositions exist.
