Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18454, here are decompositions:
- 3 + 18451 = 18454
- 11 + 18443 = 18454
- 41 + 18413 = 18454
- 53 + 18401 = 18454
- 83 + 18371 = 18454
- 101 + 18353 = 18454
- 113 + 18341 = 18454
- 167 + 18287 = 18454
Showing the first eight; more decompositions exist.
