Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145376, here are decompositions:
- 73 + 145303 = 145376
- 109 + 145267 = 145376
- 157 + 145219 = 145376
- 163 + 145213 = 145376
- 199 + 145177 = 145376
- 307 + 145069 = 145376
- 313 + 145063 = 145376
- 367 + 145009 = 145376
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 145,376 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 145376 first appears in π at position 534,470 of the decimal expansion (the 534,470ordinal-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.
