Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91012, here are decompositions:
- 3 + 91009 = 91012
- 23 + 90989 = 91012
- 41 + 90971 = 91012
- 101 + 90911 = 91012
- 149 + 90863 = 91012
- 179 + 90833 = 91012
- 191 + 90821 = 91012
- 263 + 90749 = 91012
Showing the first eight; more decompositions exist.
