Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18412, here are decompositions:
- 11 + 18401 = 18412
- 41 + 18371 = 18412
- 59 + 18353 = 18412
- 71 + 18341 = 18412
- 83 + 18329 = 18412
- 101 + 18311 = 18412
- 179 + 18233 = 18412
- 263 + 18149 = 18412
Showing the first eight; more decompositions exist.
