Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23040, here are decompositions:
- 11 + 23029 = 23040
- 13 + 23027 = 23040
- 19 + 23021 = 23040
- 23 + 23017 = 23040
- 29 + 23011 = 23040
- 37 + 23003 = 23040
- 47 + 22993 = 23040
- 67 + 22973 = 23040
Showing the first eight; more decompositions exist.
