Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43018, here are decompositions:
- 5 + 43013 = 43018
- 29 + 42989 = 43018
- 89 + 42929 = 43018
- 179 + 42839 = 43018
- 197 + 42821 = 43018
- 251 + 42767 = 43018
- 281 + 42737 = 43018
- 317 + 42701 = 43018
Showing the first eight; more decompositions exist.
