Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18382, here are decompositions:
- 3 + 18379 = 18382
- 11 + 18371 = 18382
- 29 + 18353 = 18382
- 41 + 18341 = 18382
- 53 + 18329 = 18382
- 71 + 18311 = 18382
- 113 + 18269 = 18382
- 131 + 18251 = 18382
Showing the first eight; more decompositions exist.
