Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66424, here are decompositions:
- 11 + 66413 = 66424
- 41 + 66383 = 66424
- 47 + 66377 = 66424
- 131 + 66293 = 66424
- 233 + 66191 = 66424
- 251 + 66173 = 66424
- 263 + 66161 = 66424
- 317 + 66107 = 66424
Showing the first eight; more decompositions exist.
