Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72086, here are decompositions:

13 + 72073 = 72086
43 + 72043 = 72086
67 + 72019 = 72086
103 + 71983 = 72086
139 + 71947 = 72086
199 + 71887 = 72086
277 + 71809 = 72086
367 + 71719 = 72086

Showing the first eight; more decompositions exist.
