Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90838, here are decompositions:
- 5 + 90833 = 90838
- 17 + 90821 = 90838
- 89 + 90749 = 90838
- 107 + 90731 = 90838
- 179 + 90659 = 90838
- 191 + 90647 = 90838
- 197 + 90641 = 90838
- 239 + 90599 = 90838
Showing the first eight; more decompositions exist.
