Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17638, here are decompositions:
- 11 + 17627 = 17638
- 29 + 17609 = 17638
- 41 + 17597 = 17638
- 59 + 17579 = 17638
- 149 + 17489 = 17638
- 167 + 17471 = 17638
- 251 + 17387 = 17638
- 311 + 17327 = 17638
Showing the first eight; more decompositions exist.
