Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25504, here are decompositions:
- 41 + 25463 = 25504
- 47 + 25457 = 25504
- 113 + 25391 = 25504
- 131 + 25373 = 25504
- 137 + 25367 = 25504
- 197 + 25307 = 25504
- 251 + 25253 = 25504
- 257 + 25247 = 25504
Showing the first eight; more decompositions exist.
