Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66478, here are decompositions:
- 11 + 66467 = 66478
- 29 + 66449 = 66478
- 47 + 66431 = 66478
- 101 + 66377 = 66478
- 131 + 66347 = 66478
- 239 + 66239 = 66478
- 257 + 66221 = 66478
- 317 + 66161 = 66478
Showing the first eight; more decompositions exist.
