Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43240, here are decompositions:
- 3 + 43237 = 43240
- 17 + 43223 = 43240
- 89 + 43151 = 43240
- 107 + 43133 = 43240
- 137 + 43103 = 43240
- 173 + 43067 = 43240
- 191 + 43049 = 43240
- 227 + 43013 = 43240
Showing the first eight; more decompositions exist.
