Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47140, here are decompositions:
- 3 + 47137 = 47140
- 11 + 47129 = 47140
- 17 + 47123 = 47140
- 29 + 47111 = 47140
- 47 + 47093 = 47140
- 53 + 47087 = 47140
- 83 + 47057 = 47140
- 89 + 47051 = 47140
Showing the first eight; more decompositions exist.
