Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103542, here are decompositions:
- 13 + 103529 = 103542
- 31 + 103511 = 103542
- 59 + 103483 = 103542
- 71 + 103471 = 103542
- 149 + 103393 = 103542
- 151 + 103391 = 103542
- 193 + 103349 = 103542
- 223 + 103319 = 103542
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 103 542 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
