Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18492, here are decompositions:
- 11 + 18481 = 18492
- 31 + 18461 = 18492
- 41 + 18451 = 18492
- 53 + 18439 = 18492
- 59 + 18433 = 18492
- 79 + 18413 = 18492
- 113 + 18379 = 18492
- 139 + 18353 = 18492
Showing the first eight; more decompositions exist.
