Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51920, here are decompositions:
- 7 + 51913 = 51920
- 13 + 51907 = 51920
- 61 + 51859 = 51920
- 67 + 51853 = 51920
- 103 + 51817 = 51920
- 151 + 51769 = 51920
- 199 + 51721 = 51920
- 229 + 51691 = 51920
Showing the first eight; more decompositions exist.
