Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103540, here are decompositions:
- 11 + 103529 = 103540
- 29 + 103511 = 103540
- 83 + 103457 = 103540
- 89 + 103451 = 103540
- 131 + 103409 = 103540
- 149 + 103391 = 103540
- 191 + 103349 = 103540
- 233 + 103307 = 103540
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 103,540 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
