Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80928, here are decompositions:

5 + 80923 = 80928
11 + 80917 = 80928
17 + 80911 = 80928
19 + 80909 = 80928
31 + 80897 = 80928
79 + 80849 = 80928
97 + 80831 = 80928
109 + 80819 = 80928

Showing the first eight; more decompositions exist.
