Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21934, here are decompositions:
- 5 + 21929 = 21934
- 23 + 21911 = 21934
- 41 + 21893 = 21934
- 53 + 21881 = 21934
- 71 + 21863 = 21934
- 83 + 21851 = 21934
- 113 + 21821 = 21934
- 131 + 21803 = 21934
Showing the first eight; more decompositions exist.
