Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155662, here are decompositions:
- 5 + 155657 = 155662
- 41 + 155621 = 155662
- 53 + 155609 = 155662
- 83 + 155579 = 155662
- 239 + 155423 = 155662
- 263 + 155399 = 155662
- 281 + 155381 = 155662
- 359 + 155303 = 155662
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 155,662 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
