Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91008, here are decompositions:
- 11 + 90997 = 91008
- 19 + 90989 = 91008
- 31 + 90977 = 91008
- 37 + 90971 = 91008
- 61 + 90947 = 91008
- 97 + 90911 = 91008
- 101 + 90907 = 91008
- 107 + 90901 = 91008
Showing the first eight; more decompositions exist.
