Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105272, here are decompositions:
- 3 + 105269 = 105272
- 19 + 105253 = 105272
- 43 + 105229 = 105272
- 61 + 105211 = 105272
- 73 + 105199 = 105272
- 241 + 105031 = 105272
- 313 + 104959 = 105272
- 421 + 104851 = 105272
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 105 272 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
