Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47874, here are decompositions:
- 5 + 47869 = 47874
- 17 + 47857 = 47874
- 31 + 47843 = 47874
- 37 + 47837 = 47874
- 67 + 47807 = 47874
- 83 + 47791 = 47874
- 97 + 47777 = 47874
- 131 + 47743 = 47874
Showing the first eight; more decompositions exist.
