Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25090, here are decompositions:
- 3 + 25087 = 25090
- 17 + 25073 = 25090
- 53 + 25037 = 25090
- 59 + 25031 = 25090
- 101 + 24989 = 25090
- 113 + 24977 = 25090
- 137 + 24953 = 25090
- 167 + 24923 = 25090
Showing the first eight; more decompositions exist.
