Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162040, here are decompositions:
- 23 + 162017 = 162040
- 29 + 162011 = 162040
- 41 + 161999 = 162040
- 71 + 161969 = 162040
- 83 + 161957 = 162040
- 167 + 161873 = 162040
- 233 + 161807 = 162040
- 257 + 161783 = 162040
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 162,040 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
