Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105988, here are decompositions:
- 5 + 105983 = 105988
- 11 + 105977 = 105988
- 17 + 105971 = 105988
- 59 + 105929 = 105988
- 89 + 105899 = 105988
- 227 + 105761 = 105988
- 431 + 105557 = 105988
- 461 + 105527 = 105988
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 105,988 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 105988 first appears in π at position 944,327 of the decimal expansion (the 944,327ordinal-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.
