Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18462, here are decompositions:
- 5 + 18457 = 18462
- 11 + 18451 = 18462
- 19 + 18443 = 18462
- 23 + 18439 = 18462
- 29 + 18433 = 18462
- 61 + 18401 = 18462
- 83 + 18379 = 18462
- 109 + 18353 = 18462
Showing the first eight; more decompositions exist.
