Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163642, here are decompositions:
- 5 + 163637 = 163642
- 29 + 163613 = 163642
- 41 + 163601 = 163642
- 173 + 163469 = 163642
- 233 + 163409 = 163642
- 239 + 163403 = 163642
- 383 + 163259 = 163642
- 419 + 163223 = 163642
Showing the first eight; more decompositions exist.
