Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27898, here are decompositions:
- 5 + 27893 = 27898
- 47 + 27851 = 27898
- 71 + 27827 = 27898
- 89 + 27809 = 27898
- 107 + 27791 = 27898
- 131 + 27767 = 27898
- 149 + 27749 = 27898
- 197 + 27701 = 27898
Showing the first eight; more decompositions exist.
