Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91086, here are decompositions:
- 5 + 91081 = 91086
- 7 + 91079 = 91086
- 53 + 91033 = 91086
- 67 + 91019 = 91086
- 89 + 90997 = 91086
- 97 + 90989 = 91086
- 109 + 90977 = 91086
- 139 + 90947 = 91086
Showing the first eight; more decompositions exist.
