Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18414, here are decompositions:
- 13 + 18401 = 18414
- 17 + 18397 = 18414
- 43 + 18371 = 18414
- 47 + 18367 = 18414
- 61 + 18353 = 18414
- 73 + 18341 = 18414
- 101 + 18313 = 18414
- 103 + 18311 = 18414
Showing the first eight; more decompositions exist.
