Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103140, here are decompositions:
- 17 + 103123 = 103140
- 41 + 103099 = 103140
- 47 + 103093 = 103140
- 53 + 103087 = 103140
- 61 + 103079 = 103140
- 71 + 103069 = 103140
- 73 + 103067 = 103140
- 97 + 103043 = 103140
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 103,140 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
