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.
