Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51018, here are decompositions:
- 17 + 51001 = 51018
- 29 + 50989 = 51018
- 47 + 50971 = 51018
- 61 + 50957 = 51018
- 67 + 50951 = 51018
- 89 + 50929 = 51018
- 109 + 50909 = 51018
- 127 + 50891 = 51018
Showing the first eight; more decompositions exist.
