Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155708, here are decompositions:
- 19 + 155689 = 155708
- 37 + 155671 = 155708
- 109 + 155599 = 155708
- 127 + 155581 = 155708
- 139 + 155569 = 155708
- 151 + 155557 = 155708
- 199 + 155509 = 155708
- 331 + 155377 = 155708
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 155,708 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
