Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17812, here are decompositions:
- 5 + 17807 = 17812
- 23 + 17789 = 17812
- 29 + 17783 = 17812
- 83 + 17729 = 17812
- 131 + 17681 = 17812
- 233 + 17579 = 17812
- 239 + 17573 = 17812
- 293 + 17519 = 17812
Showing the first eight; more decompositions exist.
