Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18362, here are decompositions:
- 61 + 18301 = 18362
- 73 + 18289 = 18362
- 109 + 18253 = 18362
- 139 + 18223 = 18362
- 151 + 18211 = 18362
- 163 + 18199 = 18362
- 181 + 18181 = 18362
- 193 + 18169 = 18362
Showing the first eight; more decompositions exist.
