Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91078, here are decompositions:
- 59 + 91019 = 91078
- 89 + 90989 = 91078
- 101 + 90977 = 91078
- 107 + 90971 = 91078
- 131 + 90947 = 91078
- 167 + 90911 = 91078
- 191 + 90887 = 91078
- 257 + 90821 = 91078
Showing the first eight; more decompositions exist.
