Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145134, here are decompositions:
- 13 + 145121 = 145134
- 43 + 145091 = 145134
- 71 + 145063 = 145134
- 97 + 145037 = 145134
- 103 + 145031 = 145134
- 113 + 145021 = 145134
- 127 + 145007 = 145134
- 151 + 144983 = 145134
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 145,134 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 145134 first appears in π at position 280,432 of the decimal expansion (the 280,432ordinal-suffix:nd 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.
