Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162542, here are decompositions:
- 13 + 162529 = 162542
- 19 + 162523 = 162542
- 43 + 162499 = 162542
- 103 + 162439 = 162542
- 151 + 162391 = 162542
- 199 + 162343 = 162542
- 313 + 162229 = 162542
- 433 + 162109 = 162542
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 162,542 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
