Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41638, here are decompositions:
- 11 + 41627 = 41638
- 17 + 41621 = 41638
- 29 + 41609 = 41638
- 41 + 41597 = 41638
- 59 + 41579 = 41638
- 89 + 41549 = 41638
- 131 + 41507 = 41638
- 227 + 41411 = 41638
Showing the first eight; more decompositions exist.
