Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25706, here are decompositions:
- 3 + 25703 = 25706
- 13 + 25693 = 25706
- 67 + 25639 = 25706
- 73 + 25633 = 25706
- 97 + 25609 = 25706
- 103 + 25603 = 25706
- 127 + 25579 = 25706
- 283 + 25423 = 25706
Showing the first eight; more decompositions exist.
