Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12772, here are decompositions:
- 29 + 12743 = 12772
- 59 + 12713 = 12772
- 83 + 12689 = 12772
- 101 + 12671 = 12772
- 113 + 12659 = 12772
- 131 + 12641 = 12772
- 233 + 12539 = 12772
- 269 + 12503 = 12772
Showing the first eight; more decompositions exist.
