Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145374, here are decompositions:
- 13 + 145361 = 145374
- 67 + 145307 = 145374
- 71 + 145303 = 145374
- 107 + 145267 = 145374
- 167 + 145207 = 145374
- 181 + 145193 = 145374
- 197 + 145177 = 145374
- 241 + 145133 = 145374
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 145,374 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 145374 first appears in π at position 269,348 of the decimal expansion (the 269,348ordinal-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.
