Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535922, here are decompositions:
- 13 + 31535909 = 31535922
- 43 + 31535879 = 31535922
- 101 + 31535821 = 31535922
- 113 + 31535809 = 31535922
- 181 + 31535741 = 31535922
- 241 + 31535681 = 31535922
- 251 + 31535671 = 31535922
- 283 + 31535639 = 31535922
Showing the first eight; more decompositions exist.
