Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91290, here are decompositions:
- 7 + 91283 = 91290
- 37 + 91253 = 91290
- 41 + 91249 = 91290
- 47 + 91243 = 91290
- 53 + 91237 = 91290
- 61 + 91229 = 91290
- 97 + 91193 = 91290
- 107 + 91183 = 91290
Showing the first eight; more decompositions exist.
