Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25812, here are decompositions:
- 11 + 25801 = 25812
- 13 + 25799 = 25812
- 19 + 25793 = 25812
- 41 + 25771 = 25812
- 53 + 25759 = 25812
- 71 + 25741 = 25812
- 79 + 25733 = 25812
- 109 + 25703 = 25812
Showing the first eight; more decompositions exist.
