Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145132, here are decompositions:
- 11 + 145121 = 145132
- 23 + 145109 = 145132
- 41 + 145091 = 145132
- 89 + 145043 = 145132
- 101 + 145031 = 145132
- 149 + 144983 = 145132
- 191 + 144941 = 145132
- 233 + 144899 = 145132
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 145,132 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 145132 first appears in π at position 187,010 of the decimal expansion (the 187,010ordinal-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.
