Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17890, here are decompositions:
- 53 + 17837 = 17890
- 83 + 17807 = 17890
- 101 + 17789 = 17890
- 107 + 17783 = 17890
- 233 + 17657 = 17890
- 263 + 17627 = 17890
- 281 + 17609 = 17890
- 293 + 17597 = 17890
Showing the first eight; more decompositions exist.
