Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18936, here are decompositions:
- 17 + 18919 = 18936
- 19 + 18917 = 18936
- 23 + 18913 = 18936
- 37 + 18899 = 18936
- 67 + 18869 = 18936
- 97 + 18839 = 18936
- 139 + 18797 = 18936
- 149 + 18787 = 18936
Showing the first eight; more decompositions exist.
