Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51118, here are decompositions:
- 47 + 51071 = 51118
- 59 + 51059 = 51118
- 71 + 51047 = 51118
- 149 + 50969 = 51118
- 167 + 50951 = 51118
- 227 + 50891 = 51118
- 251 + 50867 = 51118
- 269 + 50849 = 51118
Showing the first eight; more decompositions exist.
