Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47810, here are decompositions:
- 3 + 47807 = 47810
- 13 + 47797 = 47810
- 19 + 47791 = 47810
- 31 + 47779 = 47810
- 67 + 47743 = 47810
- 73 + 47737 = 47810
- 97 + 47713 = 47810
- 109 + 47701 = 47810
Showing the first eight; more decompositions exist.
