Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27992, here are decompositions:
- 31 + 27961 = 27992
- 73 + 27919 = 27992
- 109 + 27883 = 27992
- 193 + 27799 = 27992
- 199 + 27793 = 27992
- 229 + 27763 = 27992
- 241 + 27751 = 27992
- 409 + 27583 = 27992
Showing the first eight; more decompositions exist.
