Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51184, here are decompositions:
- 47 + 51137 = 51184
- 53 + 51131 = 51184
- 113 + 51071 = 51184
- 137 + 51047 = 51184
- 191 + 50993 = 51184
- 227 + 50957 = 51184
- 233 + 50951 = 51184
- 293 + 50891 = 51184
Showing the first eight; more decompositions exist.
