Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105998, here are decompositions:
- 31 + 105967 = 105998
- 127 + 105871 = 105998
- 181 + 105817 = 105998
- 229 + 105769 = 105998
- 271 + 105727 = 105998
- 307 + 105691 = 105998
- 331 + 105667 = 105998
- 349 + 105649 = 105998
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 105,998 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 105998 first appears in π at position 283,795 of the decimal expansion (the 283,795ordinal-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.
