Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25760, here are decompositions:
- 13 + 25747 = 25760
- 19 + 25741 = 25760
- 43 + 25717 = 25760
- 67 + 25693 = 25760
- 103 + 25657 = 25760
- 127 + 25633 = 25760
- 139 + 25621 = 25760
- 151 + 25609 = 25760
Showing the first eight; more decompositions exist.
