Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66406, here are decompositions:
- 3 + 66403 = 66406
- 23 + 66383 = 66406
- 29 + 66377 = 66406
- 47 + 66359 = 66406
- 59 + 66347 = 66406
- 113 + 66293 = 66406
- 167 + 66239 = 66406
- 227 + 66179 = 66406
Showing the first eight; more decompositions exist.
