Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72644, here are decompositions:

31 + 72613 = 72644
67 + 72577 = 72644
97 + 72547 = 72644
151 + 72493 = 72644
163 + 72481 = 72644
223 + 72421 = 72644
277 + 72367 = 72644
307 + 72337 = 72644

Showing the first eight; more decompositions exist.
