Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18606, here are decompositions:
- 13 + 18593 = 18606
- 19 + 18587 = 18606
- 23 + 18583 = 18606
- 53 + 18553 = 18606
- 67 + 18539 = 18606
- 83 + 18523 = 18606
- 89 + 18517 = 18606
- 103 + 18503 = 18606
Showing the first eight; more decompositions exist.
