Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43490, here are decompositions:
- 3 + 43487 = 43490
- 79 + 43411 = 43490
- 199 + 43291 = 43490
- 229 + 43261 = 43490
- 283 + 43207 = 43490
- 313 + 43177 = 43490
- 331 + 43159 = 43490
- 373 + 43117 = 43490
Showing the first eight; more decompositions exist.
