Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43658, here are decompositions:
- 7 + 43651 = 43658
- 31 + 43627 = 43658
- 61 + 43597 = 43658
- 67 + 43591 = 43658
- 79 + 43579 = 43658
- 337 + 43321 = 43658
- 367 + 43291 = 43658
- 397 + 43261 = 43658
Showing the first eight; more decompositions exist.
