Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18654, here are decompositions:
- 17 + 18637 = 18654
- 37 + 18617 = 18654
- 61 + 18593 = 18654
- 67 + 18587 = 18654
- 71 + 18583 = 18654
- 101 + 18553 = 18654
- 113 + 18541 = 18654
- 131 + 18523 = 18654
Showing the first eight; more decompositions exist.
