Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100798, here are decompositions:
- 11 + 100787 = 100798
- 29 + 100769 = 100798
- 149 + 100649 = 100798
- 239 + 100559 = 100798
- 251 + 100547 = 100798
- 281 + 100517 = 100798
- 419 + 100379 = 100798
- 647 + 100151 = 100798
Showing the first eight; more decompositions exist.
