Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3642, here are decompositions:
- 5 + 3637 = 3642
- 11 + 3631 = 3642
- 19 + 3623 = 3642
- 29 + 3613 = 3642
- 59 + 3583 = 3642
- 61 + 3581 = 3642
- 71 + 3571 = 3642
- 83 + 3559 = 3642
Showing the first eight; more decompositions exist.
