Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51030, here are decompositions:
- 29 + 51001 = 51030
- 37 + 50993 = 51030
- 41 + 50989 = 51030
- 59 + 50971 = 51030
- 61 + 50969 = 51030
- 73 + 50957 = 51030
- 79 + 50951 = 51030
- 101 + 50929 = 51030
Showing the first eight; more decompositions exist.
