Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89440, here are decompositions:
- 23 + 89417 = 89440
- 41 + 89399 = 89440
- 47 + 89393 = 89440
- 53 + 89387 = 89440
- 59 + 89381 = 89440
- 137 + 89303 = 89440
- 167 + 89273 = 89440
- 179 + 89261 = 89440
Showing the first eight; more decompositions exist.
