Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25012, here are decompositions:
- 23 + 24989 = 25012
- 41 + 24971 = 25012
- 59 + 24953 = 25012
- 89 + 24923 = 25012
- 191 + 24821 = 25012
- 263 + 24749 = 25012
- 353 + 24659 = 25012
- 389 + 24623 = 25012
Showing the first eight; more decompositions exist.
