Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25930, here are decompositions:
- 11 + 25919 = 25930
- 17 + 25913 = 25930
- 41 + 25889 = 25930
- 83 + 25847 = 25930
- 89 + 25841 = 25930
- 131 + 25799 = 25930
- 137 + 25793 = 25930
- 167 + 25763 = 25930
Showing the first eight; more decompositions exist.
