Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27888, here are decompositions:
- 5 + 27883 = 27888
- 37 + 27851 = 27888
- 41 + 27847 = 27888
- 61 + 27827 = 27888
- 71 + 27817 = 27888
- 79 + 27809 = 27888
- 89 + 27799 = 27888
- 97 + 27791 = 27888
Showing the first eight; more decompositions exist.
