Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8906, here are decompositions:
- 13 + 8893 = 8906
- 19 + 8887 = 8906
- 43 + 8863 = 8906
- 67 + 8839 = 8906
- 103 + 8803 = 8906
- 127 + 8779 = 8906
- 193 + 8713 = 8906
- 199 + 8707 = 8906
Showing the first eight; more decompositions exist.
