Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18200, here are decompositions:
- 19 + 18181 = 18200
- 31 + 18169 = 18200
- 67 + 18133 = 18200
- 73 + 18127 = 18200
- 79 + 18121 = 18200
- 103 + 18097 = 18200
- 139 + 18061 = 18200
- 151 + 18049 = 18200
Showing the first eight; more decompositions exist.
