Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162120, here are decompositions:
- 11 + 162109 = 162120
- 29 + 162091 = 162120
- 41 + 162079 = 162120
- 61 + 162059 = 162120
- 67 + 162053 = 162120
- 103 + 162017 = 162120
- 109 + 162011 = 162120
- 113 + 162007 = 162120
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 162,120 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
