Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27994, here are decompositions:
- 11 + 27983 = 27994
- 41 + 27953 = 27994
- 47 + 27947 = 27994
- 53 + 27941 = 27994
- 101 + 27893 = 27994
- 167 + 27827 = 27994
- 191 + 27803 = 27994
- 227 + 27767 = 27994
Showing the first eight; more decompositions exist.
