Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43616, here are decompositions:
- 3 + 43613 = 43616
- 7 + 43609 = 43616
- 19 + 43597 = 43616
- 37 + 43579 = 43616
- 43 + 43573 = 43616
- 73 + 43543 = 43616
- 379 + 43237 = 43616
- 409 + 43207 = 43616
Showing the first eight; more decompositions exist.
