Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105030, here are decompositions:
- 7 + 105023 = 105030
- 11 + 105019 = 105030
- 31 + 104999 = 105030
- 43 + 104987 = 105030
- 59 + 104971 = 105030
- 71 + 104959 = 105030
- 83 + 104947 = 105030
- 97 + 104933 = 105030
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 105 030 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
