Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939828, here are decompositions:
- 5 + 939823 = 939828
- 37 + 939791 = 939828
- 59 + 939769 = 939828
- 61 + 939767 = 939828
- 79 + 939749 = 939828
- 89 + 939739 = 939828
- 151 + 939677 = 939828
- 167 + 939661 = 939828
Showing the first eight; more decompositions exist.
