Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155002, here are decompositions:
- 11 + 154991 = 155002
- 59 + 154943 = 155002
- 131 + 154871 = 155002
- 179 + 154823 = 155002
- 233 + 154769 = 155002
- 269 + 154733 = 155002
- 311 + 154691 = 155002
- 359 + 154643 = 155002
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 155,002 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
