Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47242, here are decompositions:
- 5 + 47237 = 47242
- 53 + 47189 = 47242
- 113 + 47129 = 47242
- 131 + 47111 = 47242
- 149 + 47093 = 47242
- 191 + 47051 = 47242
- 353 + 46889 = 47242
- 389 + 46853 = 47242
Showing the first eight; more decompositions exist.
