Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990006, here are decompositions:
- 5 + 990001 = 990006
- 7 + 989999 = 990006
- 29 + 989977 = 990006
- 47 + 989959 = 990006
- 67 + 989939 = 990006
- 89 + 989917 = 990006
- 97 + 989909 = 990006
- 137 + 989869 = 990006
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 990,006 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
