Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47122, here are decompositions:
- 3 + 47119 = 47122
- 11 + 47111 = 47122
- 29 + 47093 = 47122
- 71 + 47051 = 47122
- 233 + 46889 = 47122
- 269 + 46853 = 47122
- 293 + 46829 = 47122
- 311 + 46811 = 47122
Showing the first eight; more decompositions exist.
