Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47182, here are decompositions:
- 53 + 47129 = 47182
- 59 + 47123 = 47182
- 71 + 47111 = 47182
- 89 + 47093 = 47182
- 131 + 47051 = 47182
- 263 + 46919 = 47182
- 281 + 46901 = 47182
- 293 + 46889 = 47182
Showing the first eight; more decompositions exist.
