Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3644, here are decompositions:
- 7 + 3637 = 3644
- 13 + 3631 = 3644
- 31 + 3613 = 3644
- 37 + 3607 = 3644
- 61 + 3583 = 3644
- 73 + 3571 = 3644
- 97 + 3547 = 3644
- 103 + 3541 = 3644
Showing the first eight; more decompositions exist.
