Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18582, here are decompositions:
- 29 + 18553 = 18582
- 41 + 18541 = 18582
- 43 + 18539 = 18582
- 59 + 18523 = 18582
- 61 + 18521 = 18582
- 79 + 18503 = 18582
- 89 + 18493 = 18582
- 101 + 18481 = 18582
Showing the first eight; more decompositions exist.
