Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43786, here are decompositions:
- 3 + 43783 = 43786
- 5 + 43781 = 43786
- 137 + 43649 = 43786
- 173 + 43613 = 43786
- 179 + 43607 = 43786
- 269 + 43517 = 43786
- 359 + 43427 = 43786
- 383 + 43403 = 43786
Showing the first eight; more decompositions exist.
