Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162724, here are decompositions:
- 11 + 162713 = 162724
- 41 + 162683 = 162724
- 47 + 162677 = 162724
- 53 + 162671 = 162724
- 83 + 162641 = 162724
- 101 + 162623 = 162724
- 113 + 162611 = 162724
- 131 + 162593 = 162724
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 162,724 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
