Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18152, here are decompositions:
- 3 + 18149 = 18152
- 19 + 18133 = 18152
- 31 + 18121 = 18152
- 103 + 18049 = 18152
- 109 + 18043 = 18152
- 139 + 18013 = 18152
- 163 + 17989 = 18152
- 181 + 17971 = 18152
Showing the first eight; more decompositions exist.
