Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42418, here are decompositions:
- 11 + 42407 = 42418
- 59 + 42359 = 42418
- 137 + 42281 = 42418
- 179 + 42239 = 42418
- 191 + 42227 = 42418
- 197 + 42221 = 42418
- 239 + 42179 = 42418
- 317 + 42101 = 42418
Showing the first eight; more decompositions exist.
