Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51126, here are decompositions:
- 17 + 51109 = 51126
- 67 + 51059 = 51126
- 79 + 51047 = 51126
- 83 + 51043 = 51126
- 137 + 50989 = 51126
- 157 + 50969 = 51126
- 197 + 50929 = 51126
- 233 + 50893 = 51126
Showing the first eight; more decompositions exist.
