Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27800, here are decompositions:
- 7 + 27793 = 27800
- 37 + 27763 = 27800
- 61 + 27739 = 27800
- 67 + 27733 = 27800
- 103 + 27697 = 27800
- 109 + 27691 = 27800
- 127 + 27673 = 27800
- 271 + 27529 = 27800
Showing the first eight; more decompositions exist.
