Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89428, here are decompositions:
- 11 + 89417 = 89428
- 29 + 89399 = 89428
- 41 + 89387 = 89428
- 47 + 89381 = 89428
- 167 + 89261 = 89428
- 191 + 89237 = 89428
- 197 + 89231 = 89428
- 239 + 89189 = 89428
Showing the first eight; more decompositions exist.
