Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91260, here are decompositions:
- 7 + 91253 = 91260
- 11 + 91249 = 91260
- 17 + 91243 = 91260
- 23 + 91237 = 91260
- 31 + 91229 = 91260
- 61 + 91199 = 91260
- 67 + 91193 = 91260
- 97 + 91163 = 91260
Showing the first eight; more decompositions exist.
