Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51124, here are decompositions:
- 53 + 51071 = 51124
- 131 + 50993 = 51124
- 167 + 50957 = 51124
- 173 + 50951 = 51124
- 233 + 50891 = 51124
- 251 + 50873 = 51124
- 257 + 50867 = 51124
- 347 + 50777 = 51124
Showing the first eight; more decompositions exist.
