Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90880, here are decompositions:
- 17 + 90863 = 90880
- 47 + 90833 = 90880
- 59 + 90821 = 90880
- 131 + 90749 = 90880
- 149 + 90731 = 90880
- 233 + 90647 = 90880
- 239 + 90641 = 90880
- 263 + 90617 = 90880
Showing the first eight; more decompositions exist.
