Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18684, here are decompositions:
- 5 + 18679 = 18684
- 13 + 18671 = 18684
- 23 + 18661 = 18684
- 47 + 18637 = 18684
- 67 + 18617 = 18684
- 97 + 18587 = 18684
- 101 + 18583 = 18684
- 131 + 18553 = 18684
Showing the first eight; more decompositions exist.
