Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27984, here are decompositions:
- 17 + 27967 = 27984
- 23 + 27961 = 27984
- 31 + 27953 = 27984
- 37 + 27947 = 27984
- 41 + 27943 = 27984
- 43 + 27941 = 27984
- 67 + 27917 = 27984
- 83 + 27901 = 27984
Showing the first eight; more decompositions exist.
