Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988000, here are decompositions:
- 3 + 987997 = 988000
- 17 + 987983 = 988000
- 29 + 987971 = 988000
- 59 + 987941 = 988000
- 71 + 987929 = 988000
- 89 + 987911 = 988000
- 131 + 987869 = 988000
- 149 + 987851 = 988000
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 988,000 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
