Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27918, here are decompositions:
- 17 + 27901 = 27918
- 67 + 27851 = 27918
- 71 + 27847 = 27918
- 101 + 27817 = 27918
- 109 + 27809 = 27918
- 127 + 27791 = 27918
- 139 + 27779 = 27918
- 151 + 27767 = 27918
Showing the first eight; more decompositions exist.
