Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145304, here are decompositions:
- 37 + 145267 = 145304
- 97 + 145207 = 145304
- 127 + 145177 = 145304
- 241 + 145063 = 145304
- 283 + 145021 = 145304
- 331 + 144973 = 145304
- 337 + 144967 = 145304
- 373 + 144931 = 145304
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 145,304 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 145304 first appears in π at position 29,028 of the decimal expansion (the 29,028ordinal-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.
