Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17642, here are decompositions:
- 19 + 17623 = 17642
- 43 + 17599 = 17642
- 61 + 17581 = 17642
- 73 + 17569 = 17642
- 103 + 17539 = 17642
- 151 + 17491 = 17642
- 193 + 17449 = 17642
- 199 + 17443 = 17642
Showing the first eight; more decompositions exist.
