Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91970, here are decompositions:
- 3 + 91967 = 91970
- 13 + 91957 = 91970
- 19 + 91951 = 91970
- 31 + 91939 = 91970
- 61 + 91909 = 91970
- 97 + 91873 = 91970
- 103 + 91867 = 91970
- 157 + 91813 = 91970
Showing the first eight; more decompositions exist.
