Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123958, here are decompositions:
- 5 + 123953 = 123958
- 17 + 123941 = 123958
- 47 + 123911 = 123958
- 71 + 123887 = 123958
- 137 + 123821 = 123958
- 167 + 123791 = 123958
- 227 + 123731 = 123958
- 239 + 123719 = 123958
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 123,958 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123958 first appears in π at position 648,893 of the decimal expansion (the 648,893ordinal-suffix:rd 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.
