Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6418, here are decompositions:
- 29 + 6389 = 6418
- 59 + 6359 = 6418
- 89 + 6329 = 6418
- 101 + 6317 = 6418
- 107 + 6311 = 6418
- 131 + 6287 = 6418
- 149 + 6269 = 6418
- 197 + 6221 = 6418
Showing the first eight; more decompositions exist.
