Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25740, here are decompositions:
- 7 + 25733 = 25740
- 23 + 25717 = 25740
- 37 + 25703 = 25740
- 47 + 25693 = 25740
- 61 + 25679 = 25740
- 67 + 25673 = 25740
- 73 + 25667 = 25740
- 83 + 25657 = 25740
Showing the first eight; more decompositions exist.
