Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995880, here are decompositions:
- 47 + 995833 = 995880
- 79 + 995801 = 995880
- 89 + 995791 = 995880
- 97 + 995783 = 995880
- 167 + 995713 = 995880
- 181 + 995699 = 995880
- 211 + 995669 = 995880
- 229 + 995651 = 995880
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 995,880 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
