Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145058, here are decompositions:
- 37 + 145021 = 145058
- 97 + 144961 = 145058
- 127 + 144931 = 145058
- 211 + 144847 = 145058
- 229 + 144829 = 145058
- 241 + 144817 = 145058
- 307 + 144751 = 145058
- 349 + 144709 = 145058
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 145,058 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 145058 first appears in π at position 595,488 of the decimal expansion (the 595,488ordinal-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.
