Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679888, here are decompositions:
- 5 + 8679883 = 8679888
- 17 + 8679871 = 8679888
- 47 + 8679841 = 8679888
- 97 + 8679791 = 8679888
- 149 + 8679739 = 8679888
- 179 + 8679709 = 8679888
- 211 + 8679677 = 8679888
- 271 + 8679617 = 8679888
Showing the first eight; more decompositions exist.
