Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668424, here are decompositions:
- 3 + 8668421 = 8668424
- 43 + 8668381 = 8668424
- 67 + 8668357 = 8668424
- 151 + 8668273 = 8668424
- 157 + 8668267 = 8668424
- 223 + 8668201 = 8668424
- 283 + 8668141 = 8668424
- 313 + 8668111 = 8668424
Showing the first eight; more decompositions exist.
