Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27944, here are decompositions:
- 3 + 27941 = 27944
- 43 + 27901 = 27944
- 61 + 27883 = 27944
- 97 + 27847 = 27944
- 127 + 27817 = 27944
- 151 + 27793 = 27944
- 181 + 27763 = 27944
- 193 + 27751 = 27944
Showing the first eight; more decompositions exist.
