Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25782, here are decompositions:
- 11 + 25771 = 25782
- 19 + 25763 = 25782
- 23 + 25759 = 25782
- 41 + 25741 = 25782
- 79 + 25703 = 25782
- 89 + 25693 = 25782
- 103 + 25679 = 25782
- 109 + 25673 = 25782
Showing the first eight; more decompositions exist.
