Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523666, here are decompositions:
- 29 + 523637 = 523666
- 89 + 523577 = 523666
- 113 + 523553 = 523666
- 173 + 523493 = 523666
- 179 + 523487 = 523666
- 233 + 523433 = 523666
- 239 + 523427 = 523666
- 263 + 523403 = 523666
Showing the first eight; more decompositions exist.
