Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25154, here are decompositions:
- 7 + 25147 = 25154
- 37 + 25117 = 25154
- 43 + 25111 = 25154
- 67 + 25087 = 25154
- 97 + 25057 = 25154
- 211 + 24943 = 25154
- 277 + 24877 = 25154
- 307 + 24847 = 25154
Showing the first eight; more decompositions exist.
