Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67420, here are decompositions:
- 11 + 67409 = 67420
- 29 + 67391 = 67420
- 71 + 67349 = 67420
- 113 + 67307 = 67420
- 131 + 67289 = 67420
- 149 + 67271 = 67420
- 173 + 67247 = 67420
- 233 + 67187 = 67420
Showing the first eight; more decompositions exist.
