Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17798, here are decompositions:
- 7 + 17791 = 17798
- 37 + 17761 = 17798
- 61 + 17737 = 17798
- 139 + 17659 = 17798
- 199 + 17599 = 17798
- 229 + 17569 = 17798
- 307 + 17491 = 17798
- 331 + 17467 = 17798
Showing the first eight; more decompositions exist.
