Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20002, here are decompositions:
- 5 + 19997 = 20002
- 11 + 19991 = 20002
- 23 + 19979 = 20002
- 29 + 19973 = 20002
- 41 + 19961 = 20002
- 53 + 19949 = 20002
- 83 + 19919 = 20002
- 89 + 19913 = 20002
Showing the first eight; more decompositions exist.
