Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11638, here are decompositions:
- 5 + 11633 = 11638
- 17 + 11621 = 11638
- 41 + 11597 = 11638
- 59 + 11579 = 11638
- 89 + 11549 = 11638
- 149 + 11489 = 11638
- 167 + 11471 = 11638
- 191 + 11447 = 11638
Showing the first eight; more decompositions exist.
