Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43178, here are decompositions:
- 19 + 43159 = 43178
- 61 + 43117 = 43178
- 127 + 43051 = 43178
- 199 + 42979 = 43178
- 211 + 42967 = 43178
- 241 + 42937 = 43178
- 277 + 42901 = 43178
- 337 + 42841 = 43178
Showing the first eight; more decompositions exist.
