Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87922, here are decompositions:
- 5 + 87917 = 87922
- 11 + 87911 = 87922
- 41 + 87881 = 87922
- 53 + 87869 = 87922
- 89 + 87833 = 87922
- 179 + 87743 = 87922
- 239 + 87683 = 87922
- 251 + 87671 = 87922
Showing the first eight; more decompositions exist.
