Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43646, here are decompositions:
- 13 + 43633 = 43646
- 19 + 43627 = 43646
- 37 + 43609 = 43646
- 67 + 43579 = 43646
- 73 + 43573 = 43646
- 103 + 43543 = 43646
- 409 + 43237 = 43646
- 439 + 43207 = 43646
Showing the first eight; more decompositions exist.
