Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100040, here are decompositions:
- 37 + 100003 = 100040
- 79 + 99961 = 100040
- 139 + 99901 = 100040
- 163 + 99877 = 100040
- 181 + 99859 = 100040
- 211 + 99829 = 100040
- 223 + 99817 = 100040
- 307 + 99733 = 100040
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 100,040 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
