Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80976, here are decompositions:

13 + 80963 = 80976
23 + 80953 = 80976
43 + 80933 = 80976
47 + 80929 = 80976
53 + 80923 = 80976
59 + 80917 = 80976
67 + 80909 = 80976
79 + 80897 = 80976

Showing the first eight; more decompositions exist.
