Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25898, here are decompositions:
- 31 + 25867 = 25898
- 79 + 25819 = 25898
- 97 + 25801 = 25898
- 127 + 25771 = 25898
- 139 + 25759 = 25898
- 151 + 25747 = 25898
- 157 + 25741 = 25898
- 181 + 25717 = 25898
Showing the first eight; more decompositions exist.
