Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27880, here are decompositions:
- 29 + 27851 = 27880
- 53 + 27827 = 27880
- 71 + 27809 = 27880
- 89 + 27791 = 27880
- 101 + 27779 = 27880
- 107 + 27773 = 27880
- 113 + 27767 = 27880
- 131 + 27749 = 27880
Showing the first eight; more decompositions exist.
