Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10042, here are decompositions:
- 3 + 10039 = 10042
- 5 + 10037 = 10042
- 101 + 9941 = 10042
- 113 + 9929 = 10042
- 191 + 9851 = 10042
- 239 + 9803 = 10042
- 251 + 9791 = 10042
- 293 + 9749 = 10042
Showing the first eight; more decompositions exist.
