Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43154, here are decompositions:
- 3 + 43151 = 43154
- 37 + 43117 = 43154
- 61 + 43093 = 43154
- 103 + 43051 = 43154
- 151 + 43003 = 43154
- 193 + 42961 = 43154
- 211 + 42943 = 43154
- 313 + 42841 = 43154
Showing the first eight; more decompositions exist.
