Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25746, here are decompositions:
- 5 + 25741 = 25746
- 13 + 25733 = 25746
- 29 + 25717 = 25746
- 43 + 25703 = 25746
- 53 + 25693 = 25746
- 67 + 25679 = 25746
- 73 + 25673 = 25746
- 79 + 25667 = 25746
Showing the first eight; more decompositions exist.
