Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25772, here are decompositions:
- 13 + 25759 = 25772
- 31 + 25741 = 25772
- 79 + 25693 = 25772
- 139 + 25633 = 25772
- 151 + 25621 = 25772
- 163 + 25609 = 25772
- 193 + 25579 = 25772
- 211 + 25561 = 25772
Showing the first eight; more decompositions exist.
