Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18452, here are decompositions:
- 13 + 18439 = 18452
- 19 + 18433 = 18452
- 73 + 18379 = 18452
- 139 + 18313 = 18452
- 151 + 18301 = 18452
- 163 + 18289 = 18452
- 199 + 18253 = 18452
- 223 + 18229 = 18452
Showing the first eight; more decompositions exist.
