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.
