Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51082, here are decompositions:
- 11 + 51071 = 51082
- 23 + 51059 = 51082
- 89 + 50993 = 51082
- 113 + 50969 = 51082
- 131 + 50951 = 51082
- 173 + 50909 = 51082
- 191 + 50891 = 51082
- 233 + 50849 = 51082
Showing the first eight; more decompositions exist.
