Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27958, here are decompositions:
- 5 + 27953 = 27958
- 11 + 27947 = 27958
- 17 + 27941 = 27958
- 41 + 27917 = 27958
- 107 + 27851 = 27958
- 131 + 27827 = 27958
- 149 + 27809 = 27958
- 167 + 27791 = 27958
Showing the first eight; more decompositions exist.
