Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186798, here are decompositions:
- 5 + 186793 = 186798
- 37 + 186761 = 186798
- 41 + 186757 = 186798
- 71 + 186727 = 186798
- 89 + 186709 = 186798
- 97 + 186701 = 186798
- 109 + 186689 = 186798
- 127 + 186671 = 186798
Showing the first eight; more decompositions exist.
