Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27946, here are decompositions:
- 3 + 27943 = 27946
- 5 + 27941 = 27946
- 29 + 27917 = 27946
- 53 + 27893 = 27946
- 137 + 27809 = 27946
- 167 + 27779 = 27946
- 173 + 27773 = 27946
- 179 + 27767 = 27946
Showing the first eight; more decompositions exist.
