Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25816, here are decompositions:
- 17 + 25799 = 25816
- 23 + 25793 = 25816
- 53 + 25763 = 25816
- 83 + 25733 = 25816
- 113 + 25703 = 25816
- 137 + 25679 = 25816
- 149 + 25667 = 25816
- 173 + 25643 = 25816
Showing the first eight; more decompositions exist.
