Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90388, here are decompositions:
- 17 + 90371 = 90388
- 29 + 90359 = 90388
- 107 + 90281 = 90388
- 149 + 90239 = 90388
- 191 + 90197 = 90388
- 197 + 90191 = 90388
- 239 + 90149 = 90388
- 281 + 90107 = 90388
Showing the first eight; more decompositions exist.
