Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102040, here are decompositions:
- 17 + 102023 = 102040
- 41 + 101999 = 102040
- 53 + 101987 = 102040
- 83 + 101957 = 102040
- 101 + 101939 = 102040
- 149 + 101891 = 102040
- 167 + 101873 = 102040
- 233 + 101807 = 102040
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 102,040 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
