Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105098, here are decompositions:
- 61 + 105037 = 105098
- 67 + 105031 = 105098
- 79 + 105019 = 105098
- 127 + 104971 = 105098
- 139 + 104959 = 105098
- 151 + 104947 = 105098
- 181 + 104917 = 105098
- 229 + 104869 = 105098
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 105,098 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
