Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72066, here are decompositions:

13 + 72053 = 72066
19 + 72047 = 72066
23 + 72043 = 72066
47 + 72019 = 72066
67 + 71999 = 72066
73 + 71993 = 72066
79 + 71987 = 72066
83 + 71983 = 72066

Showing the first eight; more decompositions exist.
