Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989906, here are decompositions:
- 19 + 989887 = 989906
- 37 + 989869 = 989906
- 67 + 989839 = 989906
- 79 + 989827 = 989906
- 103 + 989803 = 989906
- 109 + 989797 = 989906
- 157 + 989749 = 989906
- 163 + 989743 = 989906
Showing the first eight; more decompositions exist.
