Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105028, here are decompositions:
- 5 + 105023 = 105028
- 29 + 104999 = 105028
- 41 + 104987 = 105028
- 137 + 104891 = 105028
- 149 + 104879 = 105028
- 179 + 104849 = 105028
- 197 + 104831 = 105028
- 227 + 104801 = 105028
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 105,028 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 105028 first appears in π at position 468,812 of the decimal expansion (the 468,812ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
