Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18536, here are decompositions:
- 13 + 18523 = 18536
- 19 + 18517 = 18536
- 43 + 18493 = 18536
- 79 + 18457 = 18536
- 97 + 18439 = 18536
- 103 + 18433 = 18536
- 109 + 18427 = 18536
- 139 + 18397 = 18536
Showing the first eight; more decompositions exist.
