Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41644, here are decompositions:
- 3 + 41641 = 41644
- 17 + 41627 = 41644
- 23 + 41621 = 41644
- 41 + 41603 = 41644
- 47 + 41597 = 41644
- 101 + 41543 = 41644
- 131 + 41513 = 41644
- 137 + 41507 = 41644
Showing the first eight; more decompositions exist.
