Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27940, here are decompositions:
- 23 + 27917 = 27940
- 47 + 27893 = 27940
- 89 + 27851 = 27940
- 113 + 27827 = 27940
- 131 + 27809 = 27940
- 137 + 27803 = 27940
- 149 + 27791 = 27940
- 167 + 27773 = 27940
Showing the first eight; more decompositions exist.
