Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25766, here are decompositions:
- 3 + 25763 = 25766
- 7 + 25759 = 25766
- 19 + 25747 = 25766
- 73 + 25693 = 25766
- 109 + 25657 = 25766
- 127 + 25639 = 25766
- 157 + 25609 = 25766
- 163 + 25603 = 25766
Showing the first eight; more decompositions exist.
