Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43420, here are decompositions:
- 17 + 43403 = 43420
- 23 + 43397 = 43420
- 29 + 43391 = 43420
- 89 + 43331 = 43420
- 101 + 43319 = 43420
- 107 + 43313 = 43420
- 137 + 43283 = 43420
- 149 + 43271 = 43420
Showing the first eight; more decompositions exist.
