Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105228, here are decompositions:
- 17 + 105211 = 105228
- 29 + 105199 = 105228
- 61 + 105167 = 105228
- 131 + 105097 = 105228
- 157 + 105071 = 105228
- 191 + 105037 = 105228
- 197 + 105031 = 105228
- 229 + 104999 = 105228
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 105 228 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
