Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51912, here are decompositions:
- 5 + 51907 = 51912
- 13 + 51899 = 51912
- 19 + 51893 = 51912
- 41 + 51871 = 51912
- 43 + 51869 = 51912
- 53 + 51859 = 51912
- 59 + 51853 = 51912
- 73 + 51839 = 51912
Showing the first eight; more decompositions exist.
