Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18504, here are decompositions:
- 11 + 18493 = 18504
- 23 + 18481 = 18504
- 43 + 18461 = 18504
- 47 + 18457 = 18504
- 53 + 18451 = 18504
- 61 + 18443 = 18504
- 71 + 18433 = 18504
- 103 + 18401 = 18504
Showing the first eight; more decompositions exist.
