Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66916, here are decompositions:
- 53 + 66863 = 66916
- 107 + 66809 = 66916
- 167 + 66749 = 66916
- 233 + 66683 = 66916
- 263 + 66653 = 66916
- 347 + 66569 = 66916
- 383 + 66533 = 66916
- 449 + 66467 = 66916
Showing the first eight; more decompositions exist.
