Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13772, here are decompositions:
- 13 + 13759 = 13772
- 43 + 13729 = 13772
- 61 + 13711 = 13772
- 79 + 13693 = 13772
- 103 + 13669 = 13772
- 139 + 13633 = 13772
- 181 + 13591 = 13772
- 331 + 13441 = 13772
Showing the first eight; more decompositions exist.
