Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51084, here are decompositions:
- 13 + 51071 = 51084
- 23 + 51061 = 51084
- 37 + 51047 = 51084
- 41 + 51043 = 51084
- 53 + 51031 = 51084
- 83 + 51001 = 51084
- 113 + 50971 = 51084
- 127 + 50957 = 51084
Showing the first eight; more decompositions exist.
