Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43690, here are decompositions:
- 29 + 43661 = 43690
- 41 + 43649 = 43690
- 83 + 43607 = 43690
- 113 + 43577 = 43690
- 149 + 43541 = 43690
- 173 + 43517 = 43690
- 191 + 43499 = 43690
- 233 + 43457 = 43690
Showing the first eight; more decompositions exist.
