Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72986, here are decompositions:

13 + 72973 = 72986
37 + 72949 = 72986
79 + 72907 = 72986
97 + 72889 = 72986
103 + 72883 = 72986
127 + 72859 = 72986
163 + 72823 = 72986
223 + 72763 = 72986

Showing the first eight; more decompositions exist.
