Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18562, here are decompositions:
- 23 + 18539 = 18562
- 41 + 18521 = 18562
- 59 + 18503 = 18562
- 101 + 18461 = 18562
- 149 + 18413 = 18562
- 191 + 18371 = 18562
- 233 + 18329 = 18562
- 251 + 18311 = 18562
Showing the first eight; more decompositions exist.
