Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47638, here are decompositions:
- 29 + 47609 = 47638
- 47 + 47591 = 47638
- 131 + 47507 = 47638
- 137 + 47501 = 47638
- 179 + 47459 = 47638
- 197 + 47441 = 47638
- 251 + 47387 = 47638
- 257 + 47381 = 47638
Showing the first eight; more decompositions exist.
