Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51072, here are decompositions:
- 11 + 51061 = 51072
- 13 + 51059 = 51072
- 29 + 51043 = 51072
- 41 + 51031 = 51072
- 71 + 51001 = 51072
- 79 + 50993 = 51072
- 83 + 50989 = 51072
- 101 + 50971 = 51072
Showing the first eight; more decompositions exist.
