Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90490, here are decompositions:
- 17 + 90473 = 90490
- 53 + 90437 = 90490
- 83 + 90407 = 90490
- 89 + 90401 = 90490
- 131 + 90359 = 90490
- 137 + 90353 = 90490
- 227 + 90263 = 90490
- 251 + 90239 = 90490
Showing the first eight; more decompositions exist.
