Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72300, here are decompositions:

13 + 72287 = 72300
23 + 72277 = 72300
29 + 72271 = 72300
31 + 72269 = 72300
47 + 72253 = 72300
71 + 72229 = 72300
73 + 72227 = 72300
79 + 72221 = 72300

Showing the first eight; more decompositions exist.
