Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25144, here are decompositions:
- 17 + 25127 = 25144
- 23 + 25121 = 25144
- 47 + 25097 = 25144
- 71 + 25073 = 25144
- 107 + 25037 = 25144
- 113 + 25031 = 25144
- 131 + 25013 = 25144
- 167 + 24977 = 25144
Showing the first eight; more decompositions exist.
