Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25814, here are decompositions:
- 13 + 25801 = 25814
- 43 + 25771 = 25814
- 67 + 25747 = 25814
- 73 + 25741 = 25814
- 97 + 25717 = 25814
- 157 + 25657 = 25814
- 181 + 25633 = 25814
- 193 + 25621 = 25814
Showing the first eight; more decompositions exist.
