Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18050, here are decompositions:
- 3 + 18047 = 18050
- 7 + 18043 = 18050
- 37 + 18013 = 18050
- 61 + 17989 = 18050
- 73 + 17977 = 18050
- 79 + 17971 = 18050
- 127 + 17923 = 18050
- 139 + 17911 = 18050
Showing the first eight; more decompositions exist.
