Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155602, here are decompositions:
- 3 + 155599 = 155602
- 23 + 155579 = 155602
- 101 + 155501 = 155602
- 149 + 155453 = 155602
- 179 + 155423 = 155602
- 269 + 155333 = 155602
- 311 + 155291 = 155602
- 383 + 155219 = 155602
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 155,602 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
