Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72966, here are decompositions:

7 + 72959 = 72966
13 + 72953 = 72966
17 + 72949 = 72966
29 + 72937 = 72966
43 + 72923 = 72966
59 + 72907 = 72966
73 + 72893 = 72966
83 + 72883 = 72966

Showing the first eight; more decompositions exist.
