Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10642, here are decompositions:
- 3 + 10639 = 10642
- 11 + 10631 = 10642
- 29 + 10613 = 10642
- 41 + 10601 = 10642
- 53 + 10589 = 10642
- 83 + 10559 = 10642
- 113 + 10529 = 10642
- 179 + 10463 = 10642
Showing the first eight; more decompositions exist.
