Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108428, here are decompositions:
- 7 + 108421 = 108428
- 127 + 108301 = 108428
- 139 + 108289 = 108428
- 157 + 108271 = 108428
- 181 + 108247 = 108428
- 211 + 108217 = 108428
- 241 + 108187 = 108428
- 349 + 108079 = 108428
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 108,428 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 108428 first appears in π at position 632,494 of the decimal expansion (the 632,494ordinal-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.
