Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72544, here are decompositions:

11 + 72533 = 72544
41 + 72503 = 72544
47 + 72497 = 72544
83 + 72461 = 72544
113 + 72431 = 72544
191 + 72353 = 72544
257 + 72287 = 72544
293 + 72251 = 72544

Showing the first eight; more decompositions exist.
